Trying to get this ironed out before Saturday and need some help.

Problem:  Backfire through the carb.

Parts I have replaced so far; new coil, new distributor cap and rotor, and adjusted the timing.

Its an AMC 360 motor with a 3 month old holley truck avenger (with backfire protection)  

Any ideas?

Thanks,

Tony

How long has it been doing this, just start or for awhile?  Using a carb guide that I have sounds like it could be a large intermediate jet.

Just started.  I highly doubt it bad jetting.  It has to be something electrical……. I think.?

Maybe a vacuum leak or line off or connected incorrectly, leaking carb gasket?

Did you have two plug wires melt together?

Turned out to be a bad distributor gear.  Now I'm going to have to check my cam gear and timing set.  I might be able to wheel tomorrow.
