The TI you posted shows the dual keyway flywheel.....one slot is marked with a "P" and the other is marked with a "B" (on the 064) or a "X" on the 066.
The part numbers on my flywheel are 1122 400 1203 and 1122 400 1204.
That's why I was being cryptic.
So you only have one key way and it's marked P?
P is usually the slot for the rev-limited coil.
Jacob, Was over picking up parts at my dealer today and was offered some new Dolmar PC7412's at a real good price if you are interested. Seems the distributor is overstocked on the twelve inch models.
I'm only interested in the Stihls. It's bad enough having to get parts for Dolmar chainsaws let alone Dolmar demolition saws.
