I have a polaris 250 that ran and smoked terribly, did like the repair manual said
after removing the gas and oil tanks and used mixed gas to run it to try to clear the engine. The mixed gas is the correct mix. It ran a few minutes and ran out of fuel in the carb. Since then it won't start or even fire. Getting gas through carb and spark. Timing marks line up with piston at tic, thought it might off time. Even tried fuel in the spark plug hole and still won't fire. Compression is 60 lbs dry and 120 with fuel. Any help would be appreciated. Thanks.

Just as I thought, it's a POS! Cracked piston around the wrist pin and bent ring on the exhaust side. Gonna have to put in a new piston and maybe bore the cylinder. :motz:
