Hesitates!
Pelle,
Check out this website for a list of really great tuning articles
for both Holley and Qjet. The Author of the carb tuning papers, Lars Grimsrud
is a regular on corvetteforum.com. Most of the articles are relevant to C2 and
C3 corvettes, but the ones on tuning, timing, and vacuum are some of the best
I've ever seen. He really knows how to troubleshoot and explain the technical
stuff.
Hope this helps.

Good idea! (doh! why didn't I
think of this?)
I'll disconnect the pumps to see
what happens!
I'll buy an assortment of acc
pump nozzles too.
I've got a feeling that it's
running a bit too lean!?
No black smoke
puffs!

Pelle,
The problem could be the acc pump is making it too rich (too
big a shot) or too lean (not enough). Does the exhaust shoot a puff of
black smoke when you nail the throttle? The easiest way to test this is to
disable the pump and see if the hesitation get better or worse. I've only
been studying up on QJets, so I don't know how to tell you to do this, but
if the car runs better without the pump, then it's too much of a shot, and
you should go down a shooter size and test it again.

& everything's ok
as
far as I can see!? No dirt, no corrosion, no dried out old
