I have a polaris atv with a 300 2 stroke engine. It gets fuel, spark, compression, took air filter off and it's not plugged. And exhaust not plugged. Will not start. I'm out of ideas
One more thing to check is the crankshaft seal. If the seal is bad it wont create enough vacuum for the carburetor causing a lean condition. You can check by squirting carburetor cleaner in the seal behind primary clutch while cranking atv. Let me know if you require more assistance. Daniel
