Hi Denny,Thanks for the reply. What we found in the GM specs. was that for the sparkplugs ( AC Delco ) they came gapped at 60 but we reset them to 50 because we also thought that was a little much. As far as the pump shot we checked over and over and we could not even think about moving the throttle without getting a squirt of fuel. Thats when we thought a slightly larger sprayer jet would help,but it did not make much difference.The distributor was checked when the advance weight kit was installed and everything was virtually new.The fuel levels as well were checked after the replacement of the accelerator pump parts.We just seem to be missing something,Thanks again.
