Mr.Fixit:
I need help trouble shooting a carb problem.
I have a Holley 750dp Manual atop a 351w stroker.
Had the thing running great, and out of the blue
it has started back firing thru the carb. This happens
when engine is at operating temp after sitting at
a red light (idle) .When I give her the gas - POP.
Then she goes dead for a second and comes alive again,
or goes dead totally (hard to refire then). I have check for
vacuum leaks / made shure everything is snug. The back fire
happens when the carb makes the transission from the idle
circuit to the mains. Your expertise has been a big help to me in the past.
Thanks
WB
