Idles on one cylinder

[speedfreekk]

I need help my banshee does not idle on both cylinders. The left cylinder does not fire when idling or barely fires, as I give it more gas it comes back. I like the way the banshees sound when they idle and would like to get it fixed. I have equal compression, great spark, new delta reeds, new seals in the case and the case is sealed good, new pistons, I have kein carbs and swapped them from side to side, the crankshaft is a hot rod and it was in there when I bought it, it looks beat up(someone said it might be out of phase) I have looked at about everything that I could think of. I have ever swapped out he stator, coil, cdi and no diff.

If anybody has any ideas I would appreciate it, thanks

Typically your symtoms mean a plugged pilot jet. Thats where I would have gone first.

This generally means it's rich and is fouling or about to. You need to adjust your pilot jet and/or air screw settings.

Hey, your problem is in your carbs unlesss the problem followed you when you switched the carbs. I build high end engines and have a shop around Wichita, KS. Drop me a line and I will help you along. Your crank is not "out of phase" or whatever that means. Things just need a bit of tuning and you carbs are out of sync. No biggy and 1hour is all it needs more than likely. PLEASE don't change the pilots because that is not the problem.
