Dude if your having back fire threw your intake throtal body then that's the ingition timing. Theres crankcase timing and ignition timing. If you have poping coming out your tail pipe then it's crankcase timing. Or it's backwards. Lol but you know what I mean. My dude had the problem with the poping noise coming out his tail pipe when ever he would try to crank it over.
