This why I keep even the cheap saws around. To grab parts from when needed to do stuff on the cheap for occasional use homeowner.
Ran with chain brake on and clutch spring lost its temper. Broke through the brake band too.
Using PP4018 might be a 4218 for part instead of rebuilding it. Just had a slight score and had good used p+c already. Long as newer strato seems most swap.
Also needs a carb kit or a new carb. Being almost same prices.
Sold the little woodshark one yesterday too.
