Just rebuilt a holley 600cfm, vac. secondaries and it seems to be fine except when I hit the gas. I'm getting backfire through the carb. I just bolted it back on, so I havent had time to adjust the mixture or floats. Maybe that's the problem, but I thought I'd check since I wont get back to it until tomorrow. TIA for any help.
