Weed eater I know it's not a chainsaw and can get rid of it . Just fixing for a friend . What it had was back fire so bad it would knock the choke open . I was thinking coil was out of time tried a new coil same thing . Was digging for the flywheel key is were I was stuck . There is a clutch in front of the flywheel I have no ideal if the threads are R or L handed or how to get the clutch off .

FS45?

See page 13 of “STIHL Components 4140 FC, FS, HL, KM” service manual. I’ll try to copy/paste it, but you can google it up. The IPLs & IOMs are available too.

It’s a standard right hand thread, lefty loosey. Use a metric key to pull the drum, & a piece of rope for a piston stop. Then use a 2 pin clutch tool for the clutch...standard weed-eater drive end bull ****.

FW key must be cast integral with the FW, as a separate key is not shown.

It takes a t-20 torx to remove the drum,
and just tap the clutch with a hammer to the left to remove it, and use a socket on the clutch and tap it to remove the flywheel.

Should have guessed that beating it off is your preferred method!!

Hey as long as its not an FS-44 Its alright.

Were there no key fragments at all? The key is for alignment, the taper holds the time

It is part of the flywheel, it just holds the flywheel in place while you torque down the clutch.
