This looks like a problem to me Do you have a 4.5 laying around to try?


Thanks for the reply. Negative on the 4.5 PV unfortunately. Just another 6.5 which comes in a rebuild kit. Gonna see if I can find a 3.5 or 4.5 tomorrow.

Usually popping back through the carb is attributed to early ignition timing. I'd start from square one and put on TDC, confirm distributor shaft is in the proper location, then do as MR PBody said to set up your base timing.


Hope to get back to it tomorrow AM and will try all suggestions. Hopefully I will have better results to report.
