#ffffff}Holy Crap! you guys talk on levels that just
make me dispair. How the %#^! am I going to keep my
stuff on the road when I have to worry about whether
my flamerator is a zygote point above 4. What? I am
never advancing beyond a '63 split window. Chuck says
it's a tractor, and that's OK by me. Murray and I just
drove to Andrew's house, about 75 freeway miles away,
and he is just the bomb. Everything is working so well
together, but I have no idea the angle of the dangle.
And if I have to learn, I'm just going to get into
stamps. Jan's Dad left us about two refrigerator boxes
full and I really should get started. From now on,
look for me over at WWW.IGOTTABUTTLOADOFSTAMPS.COM

Okay, on the hesitation issue. How much mechanical
advance do you have set for the SVDA. It shouldn't be
more than 30 degrees BTDC. It could be that it's
advancing too far and causing the issue under load,
however when you're accelerating the vacuum signal to
the SVDA should be low. You're connected on the
left port of the 34 PICT 3 near the idle bypass and
mixture screws right?
On the second issue, you relay could be shot or your
solenoid could be shot. You could also have too low
of voltage from the battery to trip the relay and the
solenoid.

Guess what.. I went on my little 20 mile
"deer run" as I call it and stopped about 1/2 as my
Berg dipstick was flicking on at 45 mph.... so I
go back to the engine and I notice the air hose
coming from the back of the engine to the oil bath
nozzle was disconnect.. ( might be a reason it's
running hot letting the hot air into the engine
compartment) connected it then I notice that the
vacuum connection the top left of the pict 34
coming from the diaphragm of the SVDA was not
connected, so I connected it... Got in the bus ,
cranked it up and drove.
The hesitation came back just like before I
changed the plugs. Stopped the bus went to the back
and disconnected that hose coming from the
diaphragm on the SVDA, guess what , drove fine (as in
not jerking, hesitation ) when shifting from one
gear to the next. Drove a ways disconnected and
same thing (jerking and missing like at the higher
rpm's in the gears)..... Did this switch about 4 times
to make sure...... now the fun part!
Stopped the bus to disconnect the hose (final
experiment to get back home) got back the bus, turned
the key, nothing, no noise, got lights and radio ,
gauge lights all light up, not even a murmur from
the starter or solenoid. I do have a hard start relay
in it and I checked the fuse and it was blown.. no
15 amp fuse in the bus.... bummer
out in the middle of no where (close to where I
got stuck trying to chase hogs in the other bus)....
Finally a guy came by, pushed me off, got home
, (forget the cell phone too) apologized to the
wife... went out to the bus , stuck a 30 amp fuse
in the hard start relay,,,, nada... nothing.. fuse
didn't blow either.... no start....
2 problems:
Why does the bus run like crap with the vacuum
connected and run ok with it not connected.,... a bad
vacuum can? (not doing it's job? maybe) bad SVDA
Electrical (blew the hard start relay somehow
or a ground came loose) I do know if the hard start
was blown if the started would turn over. Anyone
know. Thinking that the hard start blew along with
the fuse and power is not getting to the started....
I need a beer.....

Trey: Spark plugs are critical on the VW
engine. About 9,000-10,000 miles on a set and that's
about it. I change my plugs, points and
condenser every 10,000. If you have a VW engine
"cutting out" i.e., missing at higher rpm on
acceleration the first suspect should be the
plugs. That's not necessarily always the
problem, but is the most probable.

Sammie,
Keeping my fingers crossed. I changed the
plugs (NGK) and gapped them to .026. Drove thru the
neighborhood and so far so good. No jerking
when shifting from 2nd to 3rd and 3rd to 4th.
trying to talk the wife into going for a ride but
looks like we will tomorrow.
I owe you a beverage of your choice next
time I see you.
Thanks,
Trey

Sounds to me like the plugs could be cutting out.
That's the first thing I would do; change the
spark plugs.

Right before you shift from 2nd to
3rd and 3rd to 4th, the bus jerks at the
end of the rpm spectrum. I don't have a
tach in it but at around 25 mph (in 2nd) the bus jerks
then I shift to 3rd it's ok until I get
ready at 35 to 40 mph shift to 4th, same
thing happens, bus jerks , pulsates....
The other day on the highway it started
doing this at 55 mph in 4th.... Freaked me
out. I've changed the coil, spark plug
wires twice and still same symptoms. Running an
SVDA with a compufire it in, could the compufire
be going out? I think these things will
just fail.
I'm sure everyone is out in their buses
today enjoying beautiful weather,
I'm trying to get ready for Spicewood.
any suggestions please let me know. I
did take the pict 34 off a few weeks ago and
cleaned it up, blew out all the jets and
all that..Plus took the fuel pump and cleaned the
screen and installed a new fuel filter.
