Are you sure your not 180* off?
OK this is going to sound stupid but what does backfireing tthrough the carbs?? I thought it ment the timing was to retarted. So i advanced it and it still does it. this is a fresh rebuild and I'm trying to fire it for the first time. thanks

IT was the first time i tryed to fire it so i changed it and now it fires but won't stay running and backfires thuough the top.??? I'm stumped!!! thanks
Tom
sounds like your 180 out
Plug wire switched?
Cam timing?
One or more cylinders?
Exhaust valve not opening will do the same thing.
PM me your phone number if you do not get it going.
I will call you back and we can go over the basics tomorrow.
thanks info i will do that i'm going to double check every thing and i will let you know what i found. thank you

Since you already fired it up with it out 180* you most likely already experienced backfiring, this can blow out power valves on Holly's if that is what your using might check for that.
sounds like your either 180 out, have exhaust valves not opening, or your 1 tooth off in the dist gear, and its not advanced enough.
