fuel starvation/vapor lock?

Thanks Dac. No O'Reily s but an Autozone. Maybe a cross reference.

Or if they have a sheet of cork gasket material you can make one until the real deal arrives. The original my understanding is were made of cork gasket.

Sure you don’t have a rich idle profile? I’ve had that happen. Stumble till rpms get past 1000 rpm? Otherwise it runs/drives great? Once sorted it would be nice to add a gauge too.

Rubber fuel line can get stiff enough to the point that the clamp may not seal it long before it is old enough to show cracks.

Nismou20, were the stumble symptoms always present? Mine only appear when the cars been running for awhile, worse on very hot days.
An update on the no fuel/no start issue. Purchased a generic in line fuel filter and a length of rubber fuel line. The fuel line looked ok but replaced it anyway. After installation I watched the fuel filter fill up (purposely bought a clear filter) and the car started shortly after. I havent taken it for a test drive yet to see if it resolved the stumbling problem but will do that this afternoon. Apparently my self fabricated gasket was not sealing properly? Or perhaps it was the fuel line as C.Costine suggested? Irregardless, the car is back on the road. As always, thanks for all the tips and suggestions.

Maybe wrap the fuel lines at the carbs with some of the various heat shield stuff for potential vapor lock.
