Subject: <VV> PG accelerator pump adjustment
Hello all,

I'm still fighting with that stumble on acceleration in the 63 despite
changing the entire ignition system and now even the whole engine and
accessories.  The only thing I can think of that hasn't been changed is the
carbs... so I'm looking there for the cause.

Tonight driving the car I tried accelerating from a stop with a few very
fast pumps of the pedal to get multiple squirts from the accel pumps and it
seemed to work much better.  The car now idles beautifully and runs well
once it is rolling, but still has that nasty hesitation when leaving a red
light or stop sign.

I broke out my "Carburetor Training Program" booklet and went to the
section on adjusting the accel pumps... and noticed something I had somehow
overlooked before.

>From the booklet:  "On Powerglide applications using a two hole pump lever,
setting is made with the pump rod in the outer hole.  After adjustment is
made move rod to inner hole".  Now the carbs I'm running are 65 up carbs,
and probably not from a Powerglide car... they do not have "a two hole pump
lever".  If I go digging through my "core" carbs I might be able to find
some, I think the carbs that came with this car are there somewhere... what
are the chances this is my problem?

If this isn't my solution I'm going to swap on the primary carbs from my
Corsa (known good) to verify that the problem is in fact in the carbs
before going any further.
