Chainsaw Repair

no it was the average of different posts that i read across the net some were1 turn out others 2 1/2 and still others 2. but i think the majority was 1 turn or 2 turn. tomorrow ill attempt to remove the clutch drum to see if it has broken springs on the clutch becouse i have been able to idle the saw but the clutch stays engaged. i read somewhere about putting rope into the piston than useing a wrench to remove the bolt holding the drum on. hopefully the drum will slide off after that any suggestions if it doesnt?
