Chainsaw Repair

Thank you for the replies. I should have been more clear in my op, Brokenbudget. After 3 pulls, I can pull a dozen more times but it doesn't go past 90. I can't see any scores on the piston skirt from the intake but definite scores on it through the exhaust port. I'm hoping the cylinder doesn't have similar scoring but it seems to stand to reason that it will. From what I've read of this saw, I think it will be worth repairing. Thanks again
