OK, I got motor apart and it was the "Layrinth Sleeve" that attempted to weld itself to the crank that was the problem. What I do not get is the oiling for these areas. What oils the bearings at either end of the crank? With the engine apart, I am not seeing any oil passages. somebody please help me understand...:confused:
 
It's a 2-stroke. the oil is in your fuel. That's why a very high grade, and proper type of oil is needed.
