Marty, I took the 064 to Brady's for a check-up. I feel a lot better about the looks of it now that I've seen the piston, shows some age but good overall. We did some maintenance and fixed a stripped cover bolt hole. The saw still had the old style air filter with the metal caps which we replaced with the up-dated plastic one with the built-in gasket, much better seal to airbox (this saw HAS eaten a little dirt). Also replaced the throttle trigger which had a sharp edge. Can you find another one for the same price? I showed it to the silver-back (german, 68yrs old, 6'3", 280 lbs.) and he wants one too.
