I believe that type starter was refered to as the Fairbanks-Morse type. What a pain in the buttocks they can be .

Stihl went a step further and used a nylon insert in the flywheel for a more positive engagement .Fact I have either an 042 or an 048 with this device that surprisingly has never been a problem .

I was recently given a Wards WD95 branded Mono with an AH81 engine.  FM starter is not engaging well.  Will get to that later.  Somebody welded a minibike clutch drum on top of the original saw drum so that they could drive a roller chain with it.  Didn't exactly get it squared well.  Will post a few pics when I get time.  There's still a throttle cable somewhat attached to the thing too.


Will be fun getting that clutch off.  Can't really reach the nut.  Will try knocking the bronze bushing out of the center of the minibike drum.  Hopefully that'll give enough clearance through the center to reach the nut with a socket.  If not...........I'll have to cut the snout of that drum off.

Will have to scare up a bar clamp and possibly bar studs for it.  IIRC, they were removed.  Hopefully I can make use of some parts from one of the other hulks I have....

For older saws:
Tune the H side so that it 4-strokes (burbles) at WOT unloaded and just cleans up when under load.
When you lift cutting load, the saw should immediately revert to 4-stroking.  Fine tune the transition point for the wood you're cutting.
