Chainsaw Repair

Any time that I need to remove a flywheel, I try a simpler method first.
Over the years, I have found that you can loosen the flywheel nut until it's flush with the crank threads.
With a helper, support the weight of the chainsaw by the flywheel, and have your helper tap the flywheel nut.
If this doesn't work, look at the surface behind the flywheel, determine if it's metal or plastic.
If it's plastic, find a suitable piece of flat metal to use as a backup.
You can use a large flat blade screwdriver or a small crowfoot for the next step.
Place the screwdriver beneath the flywheel, preferably under the thick part of flywheel and the flat piece of metal, or case.
Twist or pry gently while TAPPING the flywheel nut with a small hammer.
Caution and common sense must be used to avoid damage.
In most cases, the flywheel will pop free with two or three taps but if not, you may have to use puller.
I am not necessarily recommending this procedure, just describing the way I have done it for many years.

one or two taps on clutch side and flywheel  pops loose.

I have both but the 372.....and most current models are fine thread.  If I remember correctly, the 266 and some less expensive Poulans are coarse.  Regardless, they are not expensive and work very well.

I use the hammer method on the end of the flywheel also.   The most stubborn flywheels I have come across so far have always been on Dolmar saws that I have.   It takes some time of prying and tapping but eventually they all come loose.

I used a ball joint fork on a Stihl 440 once. Popped right off.

Were you able to get the fork wedged or did you use it as a pry bar.
