I like to see no less than 120psi, less than 100 and it goes to the bone pile in most cases. $1000 chop saw is cost effective to r&r a top end but a $400 chain saw is junk to me.

On a chainsaw forum I look at they claim you can clean the cylinder out with muriatic acid if it doesn't have grooves in it. Maybe Dutch, Slapper or Restrorob can verify if this works.

Yea, Dboyd, I've heard the same thing but have never attempted it myself, nor was it something that was ever attempted in the Echo/Shindiawa dealership I spent time in. You've got teardown/reassembly time(labor$$) involved and to me it just doesn't make sense to not go back together with proper parts.

I won't say that the technique doesn't have any merit, it's just that I don't know anyone who has tried it.

Piston and cylinder looked good, put the new rings in today. It runs a little better, it's usuable now, but still seems lethargic.
