I just looked at my 064 coil. It is marked bosch and has the same numbers in your original post, but not the stihl P/N I mentioned. I had to refresh my memory on this.
I was confused when I got this project saw, as it had the 3 mounting bosses but a coil that only used the top and middle mounts. There was some damage to the pickup on the coil where it had rubbed the flywheel. I wanted to determine what coil/flywheel setup I had in case I needed a coil.
All the posts here mentioned the bosch "dogleg coil" for early 064. Well they made the bosch coil with only 2 mounts also. This saw has the 1201 flywheel that matches the coil. The middle boss on the case does not match up with most other stihl coils.
If you need to replace the coil others have made adapters for the middle boss, or have used the "dogleg" 046 coil.
