Popping through carb


Nov 30, 2006
I have 302 that ran fine with a two barrel but since I converted to a four barrel it won't run worth crap.I put a holley on first and it kept catching on fire inside the carb every time it would pop. Next I put a brand new edelbrock 600cfm on it and now it doesnt catch fire it just consantly pops through the carb,the gas looks extremely yellow and i am at the very bottom of the tank is the gas old? any experience would be greatly appreciated

any chance you pulled the dizzy or rewired it? If your timimg is off or your dizzy is wired like a standard 302 not a H.O. you could have issues like you discribe. Conversely if you are running a standard 302 cam and you wire it like a 302 H.O. once again pop pop pop.
