Popping/backfire?

(1/4) > >>

gtome:
Rebuilt my carb per recipe 3 in Cliffs book for my 455 Poncho. But im getting some popping in the exaust now. No changes to the dist from the Holley and it didnt do it before. Suppose I am getting air from somewhere? Also put on an RPM intake at the same time by the way. Starts and idles well.

gtome:
Pulled the plugs and they are super black. Guess its way rich and not lean at all.

gtome:
I tried to turn the mixture screw in and it wants to die that way. But even the top of the carb is turning sooty black. Just runs like crap. Then I tried turning in the APT a half turn ( I lost the paper I had with the info I took from it when I tore it down). Didnt do much for it. The idle is all over the place. Not sure whats happening here.

TommyK:
Have you checked for nozzle drip?

gtome:
Hell no! I already lost half my hair today!! Can it be done not running??
