Carb'd Chevy 350 Question - Carb backfire

My 40 has a 78 350 installed. I run a Rochester 2 barrel carb. There is no smog stuff on it. Recently when running at moderate rpm, say 2000, engine is warm, when I put my foot into it the engine will sneeze through the carb.

My stock 40 used to do this and the solution was a new gasket around the accelerator pump, as I recall.

The only PM I have done is fluid changes, air filter and plugs. The PM was done months ago.

I run regular CA fuel.

Should I check the timing or might something be wrong with the carb?
The choke is OK and not stuck closed.

Thanks,

BigJim
