I thought about doing a little build thread on that saw. But I'm going to let that thought go.

I could show you what a crank rod looks like after that ohio guy woods port one. Let alone being a thief and steal parts off your saw.

Oh what the heck

Your work looks really clean you'd be surprised how some are willing to help one that is trying.

Here is my "effort" I wanted to play around some I don't have alcue as to what I am doing, found some pictures on the AS and said what the hell can it hurt. I started with a cylinder that already most of the fins umm .... removed made it faster out the gate....

Here's what I did to my Husky 65.. it didn't use to have windowed pistons.. goes like stink now, has TONS of port timing on it.. a bit much for if you need something that chugs along, but sure responsive on the top end now. It used to look like the 480 jug in the last pic


Jred 920 stock vs 920 super that I reworked.. didn't screw anything up on that one


Yeah, I think we've all gone through the metal on something at one point or another.. I did it to a Husky 480 jug.. didn't feel the urge to take pictures of my screwup though! It wasn't a precious piece.. there was no wrist pin clip on one side, and here's how it looked.. ran like that for YEARS, no trace of the circlip anywhere!.. it was on the "uphill" side (left) which was lucky.. I smoothed it off and it run OK, it'll get new rings here soon which will help too
