I should have placed an Atta-Boy for Dean of Washington Hot Saws a long time ago, but I was hopeing to put a few hours on an AIP piston and rings for my MS-660 before giving my findings.
Well it has been long past a few hours and the piston rings seated so smoothly, that it just didn't raise any notice, Intel today when I just couldn't reach the handle but just caught my fingers on the pull-rope, thinking to slide the saw closer to reach the handle, before the rope started to crank the engine (being lazy and not walking around a log to get the saw) When the rope didn't roll the engine over, and I lifted the saw up onto the logs I was reaching over - by the starter rope before the engine rolled over, I can say I'm happy with the piston!
Dean is a top-shelf person to do business with, he walked me right though setting the saw up right, a few tricks and checks to make the job easier. And gave a tremendous deal on a couple spare parts for my 660.
Thanks Dean!
