Once I got the jug to fit, I set up the degree wheel to check the timing.

Dang Ed, you got it done quick! I didnt think it was going to show its face here for a while yet though.

I can understand your excitement, I'm excited too! I think I can get over the week after next to get my hands on it! :rock:

Sounds good. I should have it broke in by then. :)
 
The piston had a 12mm pin and the rod had a 10mm pin. We made bushings from Ampco Brass on the lathe... basically a brass with the hardness of a mild steel. They fit nice and snug. I had to trim some off the piston skirts to clear the deck of the saw. I have .030 clearance. I opted to do this rather than relieve the case, to lighten the piston some. There is still plenty skirt not to freeport.

I trimmed more than this, this was just a start.

I am very impressed with the work so far and your vision for doing such a Mod. It shows your over all knowlege of many different brands of saws and your skills as a mechanic and machinist. I like it.

I tried to rep you but I have to spread some around.
