Chainsaw Repair

3 pulls isn't telling you anything. you pull until the number doesn't go up anymore. 90 would be the bare minimum.
regardless of compression. sounds like you have much bigger problems. I wouldn't run it until you get either the tuning or airleak issue figured out and ruined parts clean up.

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

Specs show a minimum of 130psi static compression to run right.  Good would be more like 150psi.  Sounds like you need a piston and cylinder. 

Short block includes the crank;
Echo SB1100 (replaces SB1089)

P&C w/o crank, seals and related; Echo P021010574 and Echo P021036520.   

How does that old saying go, something like; sometimes you get the bear and sometimes the bear gets you? 

Maybe the cylinder will clean up and you can get away with just a piston.  I know the cylinder plating is pretty tough on the small echos.  I wouldnt try to run it anymore untill you take it down and look.
