banshee only hitting on one cylinder

[llawndogg]

:sad: I just finished tearing down and rebuilding my banshee, with exception to the engine but when I fired it up it will only run on one cylinder! I checked for spark and fuel and compression and all seem to be working fine. It does pop and fire a little bit sometimes but for the most part it isnt working.

Try switching the plug wires and see if the same cylinder still won't fire. Check for broken reeds, check the crossover tube between carbs if stock.

I did switch the plug wires, put in new plugs, the intake is billet milled with a o ring sealed crossover tube. Im just bummed cuz im supposed to go to the dunes in two days and its not gonna happen.

Check for a blockage in your exhaust...

When you switched the plug wires what happend. Did the cylinder that wasnt running switch sides or stay on the same side?

:biggrin: Turns out that the gasket at the base of the cylinder was sucking a lot of air and it was way to lean to fire, once I fixed this problem it ran like a screamin demon. We ended up going to St Anthony and I beat up on a raptor 700 with mods. I let him go first to make it a little more fair but I beat him to the top of chokecherry by a long shot and im still running at least one main to rich!
