I have a K161 engine for sale that I believe came from a Rideamatic tractor. The engine is complete and also has a nice oil bath air cleaner. It doesn't run due to weak spark, I think the condenser is bad. Also the bottom of the flywheel shroud is rusted through so it will need to be repaired or replaced. Overall the engine is in nice shape and should run once the spark issue is solved.
I would prefer this to be picked up because I don't have time to help with shipping right now.
