The magneto is the same. from what I can tell, several parts are interchangable from the h80 to the tvm220 Like the magneto. The flywheel according to my part smart is not even listed on many of the models it does list magneto and flywheel in a unit. I wish I could say for sure. But block journals are the same, crank gears the same, rod journals are on may. I know this don't help but from what I can gather I would say it will fit. But like I also said It doesn't give conclusive proof it does. Best I can tell the only difference if any would be the taper. I can't see so much else being alike and that being different.
