I still want to know if there is a choke on this bus. If there is it could
do all the crap described.

Carl: I think is one of a couple of things on your carb. Here are a couple
of things to do.
First: On the right side of the carb there is a jet. You can see it, right
side of carb, little about 5mm looking brass plug. This is you idle mixture
jet. If it is clogged it can cause the problems you are experiencing.
Remove it with a screw driver. Take it out, blow through it with compressed
air to clean out any debrie that might be in there. Use low volume air
and/or hold on to it real tignt, you don't want to blow it out of your hand
and across the garage where you can't find it. Put it back in.
Second: Adjust the carb. To do this first back off the screw on that
ratchet looking thing until the screw is not touching the ratchet piece,
then locate the two adjusting screws on the left side of the carb; they are
inside a recessed fixture on the left side of the carb. The top one is a
large screw, the bottom one is a much smaller screw. Get a screw driver
that will fit in the recess and screw them both in until they bottom out,
not tignt, just enough to seat them. Then back the top one out 2 1/2 turns
and the bottom one 1 1/2 turn. The top large screw is the idle adjustment
screw. The bottom one is idle mixture control. Crank the engine. Then
adjust the large screw until the engine is idling properly. Then screw the
bottom small screw in until the engine starts to slow down, then back the
screw out about 1/2 turn. You can then readjust the large screw to get the
idle speed you want: backing it out increases idle speed, screwing it in
slows it down.
If the problem is in carb adjustment or mixture control this should fix your
problem.
Carb adjustment should be the last thing on a tune and all of the above is
assuming you have points and timing properly set. For example: If you have
the timing set way retarded it will cause idling problems like you have
described.
Also: A vacum leak can cause the same type of problem. But simple things
first. Make sure your points and timing are properly set (set the points
first then the timing) and then do what I said to the carb.

Denis,
As far as I know the choke is the flap at the top of the carb right? Is
there a way to test to see if that's the culprit?

We have lots of good VW mechanics on this list but they are mostly not mind
readers. Tell us what year model bus, what engine, what carb.etc.

The other Paul Smith and I have worked to get the bus back to road worthy
shape in time for T@P <http://us.mc833.mail.yahoo.com/mc/compose?to=T@P> ,
but we are getting down to the wie. Here's our problem. We have a fuel/air
mix problem that we can't seem to kick. Symptoms are a bus that does not
idle correctly and Paul has to 3-foot it at all stops. That's one on the
clutch, one on the brake, and one on the gas to keep us from stalling. The
first and easiest answer is to adjust the idle. The screw does nothing and
based on our Muir book, we cleaned the carb. Now will hold a fairly steady
idle , but it's too low. When you engage the transmission it dies. Or when
you rev the throttle, on the way back down to idle it goes too low and dies.
So far we have: cleaned carb with carb cleaner, cleaned air filter, replaced
fuel pump and rod, replace valve cover gasket (unrelated), replaced spark
plugs, checked timing, run compression test... all is good. The only thing
we havent replaced is points, but I surely would have thought fouled points
would show up in the compression test.
Any words of wisdom, we're caught between takinging it to a mechanic down
the street for God knows how much moolah, or skipping Transporters
altogether, which really means we would still come in our pontiac and just
camp in a tent.
Help!
