Tom, your hesitation is a classic example of a blown power valve.  Not sure
if you 2 bbl carb has one, but if it does, I guarantee that that is your
problem.  Further, if it is a blown power valve, there is a small kit that
you can buy to prevent it from happening again.  Power valves blow because
of engine backfire, and as I recall, you have had that problem in the past.

A super site for carb technology is located at:

Sometime back you briefly mentioned a medium truck and wanted more info.
Sounds like the same size truck as my motorhome.  If you still want more
info, let me know.
