This is a 166 i have had for a few years that needed a top end.
I had sent the cylinder to US chrome for a replate and was looking
for a piston and we all know thats not happening. I had done a
bunch of digging around to see what other piston i might be able to work.
I found the Husky 394 to be the closest but needed some work.
First i had the bore the wrist pin bore out from 13mm to 14mm and have
the clip groves recut. Now the 394 piston was .072 taller from top of
pin bore to top of piston so i made a .062 shim out of aluminum to bring
the cylinder up. You can see the shim in two of the pic,s. I ran a couple cuts and checked the plug color, looked good. so i ran the tank down after about
8 cuts. Refueled it and shot the video.
The pic,s of the piston are after the video. Everything looks perfect.
