Banging out big block
I have a 482 big block that I ran 2 nights last season with my sons holley 1050 carb on it. It ran great. I ordered a new carb that was set up for my engine and it would launch great but would bang out shortly after it launched. We tried bigger jets and several trys with no success. The next week we put his carb back on and it started banging out again. Nothing else changed from last season. We checked plugs, valve settings, timing and a different coil. Nothing was found to be bad. Any ideas?
