Got one XY-B many gallons old. problems carb and bearings. but have pinched piston and liner
Got one XZ-B 2 gallons old. just had new bearings, problems none apart from power delivery
Favorite engine is the XY I like the way it runs.
Is there any issues with doing the following..??
Using XY crank, piston,liner and botton with XZ Case (as it has the new bearings) and carb.
