Re: Carb backfiring on hard acceleration!
Too many variables.
Narrow it down to what you have changed/done for it do start doing this.
List as much info as you can.
Does it do it under light acceleration as well?
Timing retarded or advanced too far can give similar symptoms to what you have.
Although if you have just had the carby apart and reco'd it. My guess would be that it is running lean and as suggested, guessing its a thermoquad, your accelerator pump needs attention.
