showme -- Is your carburetor a Rochester B or BC (auto choke)? Or even if it isn't ... If your "rebuild" was just taking the carb apart and replacing old parts with new parts from a FLAPS "rebuild" kit ... You may not have actually addressed your issues.
You might find it interesting (if not helpful, even ..) to read
the Carburetor Issues/Rebuilding Tech Tips. Put together by our very own Jon G.
I've heard, but not experienced first hand, that the new carbs are built ... offshore ... and are lacking in quality.
If you choose to rebuild your carb again, also consider getting your kit from our fellow Stovebolter, Carbking (Jon H) at
The Carburetor Shop.. He will send you a kit made for your specific carburetor, not a one-size-fits-all generic kit with a bunch of offshore parts you won't need.
