"Hello all. New to this forum,
"Hello all. New to this forum, Hopeing for some help here. I have a 7.4L magnum 330 on my second time out this year it started poping back throught the carb when the rpm reach over 2000rpm. I have drained the gas and replaced with fresh pump gas. Changed the fuel seperator/filter. Replaced the sparkplugs, checked the distributor cap and rotor,(I did notice some rust on the pickup but was told that is normal), checked the timming and rechecked the timeing and still have the same problem. This engine was replaced in 2005 with a jasper engine and has less than 50hrs on it. It has a quadrajet carb and thunderbolt ignition. I sure would apprediate any ideas on what may be wrong. Thanks David"
