Since several private forums like JLA Enterprises have begun copying all
we say and do on alt.autos.corvette and getting their piece of
advertising dollars for it, while we the originators of the information
get nothing, several have begun to migrate away from here so you may not
get a lot of helpful answers.
So to JLA and the others like them I say...

**** OFF!!!


Having said that, there could be multiple reasons for your stutter. It
could be fuel, ignition, or valves float due to improper valve lash or a
bad lifter or two (not likely, but possible, besides it would make lots
of noise and run very badly at idle, if this was the case).
Sounds as if you already ruled out ignition, so fuel delivery is the
next more likely cause. Fuel filter, vacuum leak, carb adjustment. I'd
start with those first, then move to the more expensive, more difficult
possibilities.
Are you sure it's a Weber Carb? I can't say that I've ever seen a single
Weber carb for a small block, or a big block for that matter. Is it one
of those nifty multiple two barrel setups, or what?
