My 96 600 triple won’t run on all three cylinders. It has spark on all plugs and have swapped them to the middle which is the one without spark. I’ve swapped wires as well. It has 120-130 compression on all of them. It’s getting gas to the carb. Swapped the carb with the one next to it and didn’t fix anything and stayed in the middle cylinder. I’m stuck and don’t know what to do. I am new to polaris and have a little bit of time working on Polaris’s as my friends have some. Any feedback can help thanks.
