Rebuilt Carb backfire HELP!

909 Views 4 Replies 4 Participants Last post by  BradleyBergstrom
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.

did you change the timing any? It could be a bit retarded or possibly your accelerator pump is out of adjustment on the carb. Maybe some of the carb gurus will step in on this one.

Still tuning for 8.30 in the 1/8th or 12.99 in the 1/4. Whichever comes first.....
