I have a 91 club car with a KF82 flathead motor that was running before I replaced the rod in it and when I put it back together now it won't start. It is backfiring through the carb. I have aligned the marks on the camshaft and even tried turning the cam 180 degrees to see if that would make a difference. It has good strong compression and consistent spark. The only other thing I can think of is that I switched the flywheel with the one off my 86 Club Car which also has a KF82 motor, Could that be the reason this engine won't start? I have been working on this for several weeks now and am at my wits end with it!! Any suggestions would be greatly appreciated!!
