Hello. My name is Tan.

Could I get the engine model number please?

Is this a 2 or 4 stroke engine?

Has the engine been sitting? Is this carbureted or fuel injected?

L 100371 third one is 6H5K. It is a 2 stroke engine. It has a carburetor. No has been used several times this year. Was on the lake last Sunday.

Ok we need to start with a spark and compression test first. The compression must be 100+ psi with no more than 10% difference between cylinders. The spark must jump a 7/16" gap on a spark gap tester on all cylinders.
