Unfortunately no. An M magneto rotates the opposite direction from a W9.

Are you sure? I thought just the diesels spun backwards.

you bet it will, same mag.
the diesel engines mag turns opposite direction due to an idler in the timing gears thats the only diff., so dont get the 2 mixed up.

Rustred is correct. Diesel and gas ignition have the same rotation in the 9 series. They are opposite in the 6 series. This also applies to distributer pump selection.

Yes. All the diesels and the W9 gas mags rotate opposite the other IHC magnetos.

Note that the advance is different on the CCW mags between the gas and diesel 9 series applications -- the gassers take a 35 degree advance impulse coupling and the diesels take a 15 degree advance.

Sorry, the advance post wasn't there before I started typing. I was thinking there woudl be advance issues if you used a diesel mag.

Mark"s Magneto Service will exchange the 15 degree impulse cup for a 35 degree one for a nominal price. I did that with a W9 gas mag that I had so I would have a complete spare mag for my MD.
