Power Unit to Cub engine swap

Postby yellowcub » Thu Mar 18, 2021 3:13 pm

My Cousin wants to do a Power Unit to Cub engine swap. Will it swap over or not? Also, the Power Unit engine needs the smaller of the two engine valves, is that valve an exhaust or intake valve ? Thanks.

More and more people are collecting power units, think about keeping the power unit as a power unit and use a replacement engine someone is selling from a parted out cub as a replacement engine!

Yes, A C60 engine from a power unit will fit a cub tractor!

The larger valve is the intake, the smaller is the exhaust!

Good luck!

the flywheel is different.
When you only have 9 horsepower you need to know the names of all of the ponies!
