Thought I had better get a thread going on this and some pics for you guys. I'll post some more on this this evening. This engine will go into Steve's Craftsman II we repainted. But I may change frames and use the Craftsman III with electric lift. Might be easier to pull the lift and put it on his frame. We'll figure that out later.
So far, I have taken the 422437 1209-01 down to removing the crank and cam. The donor engine (42A707 1237-01) has the # 2 piston and rod out of it. So far the only crank difference I have seen is the PTO end is 3/8"~ longer on the vertical engine. May need to make a spacer for that difference so I can have the electric clutch back on there. That will be addressed as I put it on. I'll probably cut a piece out of the pulley shaft that was on it for that.
