JBugs Video Series
Turn Key Assembly - Part 2 - Carburetor, Fuel Pump, and Alternator:
Video Overview:
With most of the engine tin and fan shroud fit to our 1600cc EMPI Unassembled (but now assembled) Long Block Kit, Sam pulls the fan shroud and some other items off the engine so that the rest of the components can be installed. The fuel pump and alternator stand are installed along with the oil filler. The intake manifold is installed, followed by the carburetor, and then the oil cooler is attached properly with some replacement studs, as the original pieces ended up getting stripped with some faulty hardware. Then Sam attempts to install the fan shroud with the alternator, realizes he got ahead of himself and pulls off the carburetor, and so on and so forth! He even covers some additional modification that is often necessary with aftermarket components, and does some more engine tin trimming along the way. Sam offers some tips about setting the carburetor choke, fitting spark plug boots, explains the difference in upright and doghouse fan shrouds and other little tib bits like making sure that your spark plug air boots are in place properly. By the end of the video Sam has the engine JUST about ready to fire up for a break in run, short of mounting the coil and setting the flywheel end play.
Video Transcript:
hi I'm Sam with jbugs.com and we're
going to get our unassembled but now
assembled long block turned into a
[Applause]
turnkey so in our last video we got all
of our engine tin locked up clearance
cut ground feat on and fit so with
everything fit now we will pull
everything on the top side up and off so
that we can get our intake manifold
carburetor and all that stuff in place
at which point then we can come back and
drop this on so let's uh start taking
things
apart we can start with our fuel pump
and our generator stand SL alternator
stand we've got some gaskets that come
with a fuel pump which are actually a
little bit thicker than the L ring
German gaskets I do like thicker gaskets
to help lower the pressure on these so
I'm going to go with
those and to prevent this thing from
possibly getting locked into the engine
case I like to grease these guys
and a little bit of grease on this even
though this is going to get oiled
definitely not going to hurt
matters like so big dab of grease in
here packed with protein Snickers
satisfies
them remember 14 foot PBS is actually
quite
tight just like that c CC fins pointing
down that is the correct orientation and
just like intake manifolds have that
little raised lip if your oil deflect
plate has that little lip you do not
need to run paper gaskets it's
redundant our stand filler and just
because there's going to be shavings
when we thread this into here I like to
thread these off the
engine intake manifold gaskets for a
single port happen to
be the right diameter
to fit on that ever so nicely oh look at
that and now our vent points up let's go
with that pointing up which is a lot
better than pointing
down
and like that and throw a cap on
there 14 footb if you guess 14 you are
correct put a little cap on there for SA
Intake Manifold
keeping intake manifold I think it's
going to be our next step we've got
original style metal gaskets I think the
paper ones the thick paper ones actually
seal better but these go on and off much
easier than the paper gaskets and since
this is going to be a test rig where we
might put on different carburetors and
everything else I'm definitely going to
be using metal gaskets if you have
original heads that have the alignment
dowel it's been a long time since I've
seen them but they are out there uh
we've got our paper still in here and
there let's get our boots and clamps
ready to
[Applause]
go there we
go 14 foot
PBS and these are the fun ones cuz then
you got to come in here with a wrench
and just sit here and go clink clink
clink
clink idle solenoid we'll keep it
protected for now fuel Inlet choke you
guys have seen me work on these
before I want to say these are twelves
so I'll have to go get a
12 so we know we're at top dead center
number one our rotor's pointing right
here from our number one spark plug
number
one and I'll push these on and then I
like to make certain that I push that
wire in all the way so I know it's got a
good contact way down
below this is number
two number
[Applause]
three and number four
[Applause]
in the top two a filter two a hose to
our fuel tank so tight that they rarely
need a hose clamp especially on the
inlet side the inlet side is not
pressurized but for safety sake don't
feel bad if you run a hose clamp I often
do however on this side because running
this same size fuel hose on that Inlet
is very difficult I'm going to go with
this
again this is pressurized so we
definitely want to run clamps on here
and I will get some hose clamps for that
if I've got them here awesome if I don't
I will get them on before I start it now
Oil Cooler
I've got some oil cooler adapter studs
so we're going to go back track to where
we should have kind of started yesterday
but like you guys at home when we have a
problem sometimes it delays so we've got
that problem situated we've got two new
oil cooler studs in our oil cooler I am
using standard nuts and spring washers
this time instead of flat washers and
nylocks to tighten these guys in and I'm
going to put those on to 5 foot lbs of
torque now that we've got our oil cooler
on we do have our Hoover bit in place we
are going to put our fan shroud back in
place note that I do have bolts on here
instead of screws because now that we
have our end castings in place it will
be very hard to get a screwdriver in
there well guess what I might
have some issues doing this with that
carburetor in place I got ahead of
myself this has got to come
off all right now that our carburetor is
out of the
way get our fan TR lined up there make
sure we're place over on this side in
the sheet metal there in the sheet metal
here in here and there we go
in there fan still spin
smoothly tighten up our
clamp and these guys honestly I'm going
to flip these around I did spin our
distributor 90° I didn't like the vacuum
can all the way out the front instead of
this being number one this will be
number one and this just brings this in
line with this a little bit more
commonly positioned for people that are
familiar to using the 9s let's just play
around because I hate when sparkk plug
wires look a mess since the aftermarket
shrouds don't have the clips for the
spark plug wires we'll do it like that
make it look a little bit
Cleaner number
two I'm and Boot and then push the wire
in all the way number
three and number four there we go
beautiful this wasn't going to be a test
engine I would drill this fan shroud I
Mount our coil right here however seeing
as this is a test engine and we might
end up putting on a dual carburetor kit
or something else I am probably
depending on the length of our coil wire
hopefully I can mount our coil right
here again only because this is a test
engine I wouldn't do this on a engine
I'm running on anything else if I was
running dual carbs I would probably
mount it down on the case but yes that
will do nicely so let's do that I'll
have to get some nut shirts for that but
we'll get there I like fuel injection
style hose clamps instead of warm gear
style these are full circle clamps and
they pinch together they just get a lot
better grip on here if it was sitting up
here and this was going down to our fuel
pump I want that clamp like so there we
go throw our carburetor back in
place good and tight and I'm going to
point it up like that so easy to get
just like we thought about it ahead of
time and did
it piece of vent
hose actually that probably helps it a
little bit more if we come out there
there we
go there we go and while I've got this
Choke Adjustment
off and that open I'll show you how to
adjust a choke these three screws right
here we're going to loosen these three
screws and then with our carburetor open
we're going to rotate that assembly to
open or close this choke it's probably
overkill for these screws but let's see
if it
fits this choke was set right about
there and as I loosen the screws it came
open so what this does is there's a
little spring coil in here that heats up
and as it gets hot it loses tension and
then it allows this butterfly right here
to go straight up and down so that would
basically mean that our choke is open
for a throttle we can see that this is
what operates this
now first thing in the morning is when
you want to check the adjustment on your
choke basically the coldest time of day
that you typically drive so with these
three screws loose and where you can
rotate this upper butterfly rotate it to
the point where it just closes you don't
want to Spring tension that because then
it's have to get really really hot for
that thing to actually open up and
rotate it to the point where it's just
closed and then we'll hold
it and snug down our screws
first thing you do in the morning before
you hit the key is hit the gas once that
does two things you send a squirt of
fuel down the intake manifold and you
close the choke now turn the key in the
engine if it's tuned properly should
start right up and idle and then as the
engine warms
up
this will slowly open and that's how you
adjust the choke now I can get to the
Fan Shroud
last C couple screws one here one here
and one on the back side of our Hoover
bit we'll start with these guys on
either side and this one's not horrible
if you had a flathead screwdriver cuz
numbers one and number two sit further
forward the number three and number four
but you cannot get to this guy with a
screwdriver but from the factory
Volkswagen use standard Flathead sheet
metal screws in those locations and
ideally you leave these screws in when
you're dropping the fan trout in place
because now otherwise it's a big pain in
the tus now if you weren't on an engine
stand this little screw here would be
easy to get to but we're on a stand so
it's not so I'm going to do the same
thing I'm going to put a bolt in here
instead of a screw and that holds our
fan shroud to the Hoover bit let's do
some further investigation on this guy
here this little guy does not go here or
here goes here happens to be the perfect
length oddly enough it's this perfect
link for that too this seal seals this
Edge right here and we can do one of two
things we can put it on here which we're
going to
do and then that foam goes right there
so that
seals This
Groove and that space right there and
why they didn't just make that flat I
don't know but despite being a
aftermarket copy it is a copy and
Volkswagen did them the same exact way
now we've got this sealed here we've got
our Hoover bit to seal across the bottom
and all this air that gets blown through
here this super hot air will get now
blown out through here and through here
this is a part of that dogghouse oil
cooler system because prior to this this
oil cooler was in line here so the air
would come here on an upright shroud the
air comes in blows through the oil
cooler which is in here so the air comes
in blow go through the oil cooler that
air is now hotter and then blows down
over our head and our cylinders now this
is an air cooled engine we're trying to
cool this Engine with hot air that
doesn't make sense Volkswagen realized
that and in 1971 they debuted the
dogghouse this is the dogghouse this is
not the dogghouse fan shroud dogghouse
the dogghouse is
behind the fan shroud now the air goes
through here sealed off by our Hoover
bit sealed off by this piece of rubber
this piece of foam this piece of foam
exits down here out of the engine
compartment because this is sealed off
right here so hot air comes in through
and out of the engine compartment not
heating up our head or trying to cool
off our head with hot air all right back
to the front side spark plug boots from
the factory These Boots are normally
just pushed on by a machine or otherwise
maybe and they're pushed on way down
here when you actually put it in that
boot gets pushed into the cylinder tin
and then air can actually come out you
don't want you want all the air up here
to be pushed that way not around here
anywhere when you're putting on your
spark plug ends shift that boot all the
way up and even pull it
back then clip it in place and then push
your boot back in place so that that
hole gets covered up as much as you can
not that this engine is actually going
into a car but if it were we wouldn't
want to forget our accelerator cable
tube with the aftermarket shrouds and
honestly even with the original fan
shrouds it seems that the hole in the
Shroud is too large and well I can't
demonstrate this way because it's just
running into our engine stand but this
can actually slide through the fan
shroud so I take a large diameter 8 mm
washer and Slide the tube through the
fan shroud where it would come back here
and through this convenient hole in the
front engine tin so that's what that
hole is there for this hole is for our
exit tin this hole is for our reverse
light wire we've got a new correctly
sized alator belt 11.3 by 912 get that
put in place underneath our lower
pulley we'll pull off this nut and lock
washer make certain that this spacer is
in place the spacer is not in place a we
don't sell them separately so that's the
hard part but B then your pulley will
end up destroying your
alternator real important and you'd be
surprised how many people get this
incorrect they figure oh the belt only
needs three shims to set the correct
tightness I'm going to put three shims
in I'm going to put the pulley front
side in place and I'm going to tighten
this on and then everything's good to go
well it's not with those three shims in
place it still wobbles you need 10 shims
total whatever shims you don't use here
put them here but you need 10 shims
total three here seven here five here
you put the other five here if you put
two here put eight here if you put eight
here put the remaining two here but you
need to have 10 shims total always
otherwise this will not be able to
tighten the pulley enough do seven and
three a little tight so we're going to
loosen that
up put all 10 shims
in that's better again I'm Sam with
Exhaust
jbugs.com and we've got our empy
unassembled long block assembled and now
ready to run for the first time thanks
for watching guys we'll see you in the
next one wait wait wait wait hold on we
can't run this thing without an exhaust
we're going to go with some J tubes so I
got some J tubes we don't need heater
boxes in the shop and I'm going to go
with a new exhaust this is the exhaust
we're going to run after I pull off this
rear engine sheet metal put on some
exhaust gaskets get everything mocked up
Loosely but let's do that real
quick exhaust gaskets conveniently
enough I couple C them with the engine
gasket kit russle this guy
in we're going to put one side On
Loosely
there we go put some J tubes on there's
a long j tube and a short j tube
otherwise they almost look virtually
identical this cylinder head sits
further back so it gets the long j tube
and that side gets the short one some
fresh gaskets on the back exhaust ports
right now what we're most concerned
about is our clamps Crush ring ceiling
ring clamp clamp bolt with washer bolt
with washer spring washer spring washer
nut and nut and this will install with
the crush ring towards the j tube faces
away from the exhaust like
so now that I got everything lined up
I'll go through and bolt down our
flanges here at the heads either side
and then we'll put our clamps on and
these are 14 ftlb as
well not a whole lot of room in this
curve
here we'll get our clamp set up take off
one side ceiling ring Crush ring clamp
goes over all of that that's one side
down me go get the other side set up
Muffler clamp bolts oh wow 7 foot lb
they're bumping it up from five I don't
know about all that running it down to 7
foot lbs just seems a little bit
excessive for
me that clamp is getting that bolts I
I'm not no
now now that we've got our exhaust on
we're going to get our heat Riser set up
these things just aren't really perfect
out of the box but they work with some
Heat Riser
modifications like everything else he's
a little bit out of position I need to
cut maybe 38 of an inch off of it so
that this Edge lines up there however
once I adjust the
shape it actually lines up relatively
well other than the fact that it's kind
of not sitting quite
Square there we go that's better nothing
that a gasket can't handle so it's a
good thing I did not cut that because
now that's all but ready to go we're not
going to do anything bolting on that
because we still have to cut this out
for that so what we're going to do is
get both sides ready then we're going to
go through and Mark out the pattern on
here that we want to cut out out couple
things right off the bat my clamps here
kind of in the way so let's move those
out of the way based on how far that
thing's sticking over and that thing's
just like long as can be I've got about
one Sharpie this way or about half
harmonica thickness and how far that
thing is going across there it's only
see if this thing leaves a groove on my
finger I can touch the tip of the bottom
recess with that and well I could feel
it right about there on my finger so
that's only how deep it can go to there
I'm going to cut this off right about
there and you don't have to do this with
all intake
manifolds or all heat
risers but depending on which supplier
we get these from at any particular
Point sometimes you'll actually have to
cut these tubes sometimes you'll have to
cut these tubes and in the future we're
hoping that you won't have to cut
anything hey hey hey all right so now
that we're in the center hole much like
we had on the other one we're up short
here but if we bend
it just like that so now we've got that
in place and that in place front engine
tin back
in and I'm just going to tighten a
couple of them because I'm just going to
take this thing off in a moment once I
get this scored in this scor where this
needs to be cut that to give us an
outline of what we want to cut out for
our heat
Riser now we're going to pull this off
again like
so like so
[Applause]
there we go under that over that yeah
that seems to be pretty good as does
that
nice and all the screws in by hand
except for this guy back here cuz this
guy's it's just you can't get your hand
back there I guess if you wanted to do
stew My Method but still make it
removable you could do a little small
slice on the back just in line with a
tube so that it can be pulled in and out
like this tin right here we're just
going to do a snap like that that looks
a lot better doesn't it
and it's now removable these exhaust
gasket kits are intended for use with
stock exhausts they come with hex head
bolts which would thread into the
muffler well I have to put nuts on the
bottom side of these so I'll do that but
I will use those they also come with
these sheet metal screws that would have
held all the deflect tin in around the
exhaust
port and with that
folks
now we have an unassembled
m600c long block and with our long block
completion kit and a couple other pieces
and brackets and a whole lot of
modification and work we've got this
assembled and ready to fire for the
first time that'll be coming up in a
later video in the meantime thanks for
watching oh shoot I still got to mount
the
coil and set the end play in our next
video we'll see you then
