    i wanna see what you guess think is needs. The motor didn;t start and to make a long story short i gt it running. It doesn;t smoke until i bring the throttle above 1/4ish and then at 1/2-full throttle is smokes like a banshee. What you think it needs. Thanks LawnInOrder

    I'd say a new set of piston rings but the cylinder might need to be honed and a new piston put in. You would have to pull it apart and get some measurements.

    What color is the smoke? What color and condition is the spark plug?

    A cylinder leak-down test will tell the story better than guessing.
