064 coil problem

[L34]

Sounds like an 660 AM wheel,it has a larger taper the same as the poly wheel.
An original 066 ally wheel will fit.I have one on an 064 saw.
You need to use an 066 starter as the 066 wheel is wider than an 064.

064 and early 066 use the same crank.
Later 066 have a larger taper so wheel will hit case before it seats on 064/early 066.

The main combos on 064s are:
Flywheel: 1122 400 1201/Ignition: 1122 400 1300

Flywheel: 1122 400 1203/ Ignition: 1122 400 1311, 0000 400 1300, or 1122 400 1303, depending on which slot the flywheel is on.

Flywheel: 1122 400 1204/ Ignition: 1122 400 1303 (Rev-limited CDIC coil)

Gday All. I have 064AV, has fitted coil no: 1122 400 1303, the longish looking one. I notice the right side casing mounts have 2 differing threaded positions, is that to indicate it will take a 0000 400 1300 coil. Hope so! look forward to some advice. R. Stihlskin
