Backfire through the exhaust or the intake?
Fiat ,sounds like intake....
Check your shooters (and the little check valves below them) and also your linkage to the accelerator pumps. Sounds like not enough pump shot.
Thanks Fiat !!
will check this out, I have been having some trouble with my linkage adj. :wink: I was only worried about getting WOT not part throttle :hammer2:
I had the same thing, adjusted the slop out of the pump arms and it fixxed it. :rollside:
Yeah..that is what I meant by checking the linkage. Slop in the pump arms. My carb lingo is lacking.

Now that is funny.
What causes a blower motor to backfire through the exhaust?
