Difference Between Chappy LB80 Motor vs. LB50 Motor

Hello,

I have an LB80 with a crankshaft that has its thread pretty much chewed up. I have an LB50 motor and I figured I swap out some of the main parts like the transmission, cylinder, piston, electrical. I am counting on the fact that the engines are pretty much the same except perhaps for those parts.

Does anyone know if there are any major differences between the two engines besides the cylinders, pistons and carbs?

Thank you,

Jeroen
