Stihl 066 flywheel

[rob066]

I have a flywheel from an old style 066. This is the one from the smaller style crank with the aluminum flywheel. I was wandering why this flywheel has two key way slots. I think they are marked with an x and a p. When installing this flywheel which slot would I use.

It has two slots to accommodate two different styles of ignitions. So, in order to know which slot to use, you need to know which ignition you have.
