Re: I4 magneto will it fit cub
I believe it can be bolted on and the engine will run. But the lag angle is way wrong for the Cub engine. You wouldn't be able to get the timing right. I don't know if you could overcome the problem by using a J-4 impulse coupling.

Re: I4 magneto will it fit cub
Lag angle/advance for the H4 is 35 degrees for gas tractors. Lag angle for the Cub is 13 degrees. So, not work.
I have an excuse. CRS.

The I4 Mag has a different spark advance than the J4.
