i pump the gas a few times. start it. let it stall then start it up and keep it running for a minute or so and its fine.




Exactly.

My 71 340 Duster has a Holley 650 DP with no choke, 73 340 Dart Sport, same thing, Holley 650 DP with no choke and the 71 RR 440 six pack with no choke. All work exactly as described above. Even the 71 Demon 340 with factory TQ and choke is pretty much the same way, but with more cranking after sitting a long time. Sometimes I just pour a little bit of gas down the carb to avoid all the cranking. But I've never had all the plug fouling like the OP has.
