Hi guys, I need some help with my snowmobile I just dug out of my dads shed a few months ago. Its a 2001 polaris 550 trail indy sport and it wont start no matter what I do. I cleaned the carb, fuel pump, blowed all the gas lines and cleaned them, drained the old gas, put new gas, new oil tank w/ oil, changed crankcase oil, new fuel valve, good compression and spark to the plugs and still won’t start. Any ideas?
