Ive got a 99 zl 600 i picked up was only running on one cylinder half the time i thought the float was getting stuck tore it apart and got it all cleaned up i am still having the same problem any ideas??

 

If it has spark and fuel supply isn't the problem,I think I'd check compression against the other cylinder just to eliminate compression as the problem.

 

Shoot starting fluid down the plug holes (liberal amount) for both cylinders and fire it up...if it sounds like both cylinders fired then you can feel pretty confident it's fuel delivery and not ignition/compression...
