Hi tchild,
my name is Dennis Gladx and I can assist you with the problem of getting the sprocket off of the crankshaft of your chainsaw.
To remove the centrifugal clutch and sprocket you unscrew it from the
crankshaft and it has a left hand thread. Also a little trick to remove anything from a
crankshaft that could turn while you want to unscrew the item, Remove the spark
plug and insert some rope into the cylinder for the piston to squeeze against
and you will jam the piston without damage.
Glad to be of assistance Please rate this solution because I can learn from your rating. Thank you

Outboard drums (drums on the outside of the clutch) are held on by a nut or e-clip.
Inboard drums are held on by the clutch which is threaded onto the crankshaft. And there is the challange.
***NOTE all chain saw clutches have LEFT hand threads, so, rightey loosey, lefty tightey. (just backwards from everything else)
*** NOTE #2: DO NOT USE AN IMPACT GUN
this will most certainly shear the flywheel key or damage the flywheel !!!!! (after 35 years, you can ask me how I know that, LOL)
1) Use a piston stop to hold piston from moving: THIS IS A MUST !!!
Ok, so you do not have one, let's make one.
a) remove the spark plug
b) insert a piece of recoil rope into the cylinder hole, leaving a tail to remove it by. (rope, large shoe string, anything that is soft, that is aprox 1/4 to 5/16 in diameter to place into the spark plug hole to help the piston to stop it's travel by filling up the empty space. Just make sure you can remove it later)
c) secure the saw (extra set of hands may be needed) and with a suitable wrench on the clutch center, rotate the clutch to the right until piston comes to a stop. With a hammer, tap the wrench to aid in rotation. This can be very difficult, and may take several taps.
d) after removed, inspect and grease the drum bearing before re-assemlby.
e) upon re-assembly of clutch, tighten by hand only, NO hammer required. The force of the chain will tighten the clutch.
f) remove the rope, and re-install the spark plug.
