Looks good Brad,
You still have the Wiseco piston in it.
I believe this was the saw with it.
If i'm correct.

Is there any White Oak there at that property, I need some new trailer planks! I can't find a white oak around here to cut out of.
We number collectors thank you, Brad.Here are a few specs on the saw for you number collectors.
Stock
Exhaust - 97°
Transfers - 122°
Intake - 80°
Blowdown - 25°
Squish - .021"
I had no issues with the stock port timing, plus it's a worksaw. So I didn't go in to change port timing. I did end up lowering the intake to 82°, just cleaning up a little lip on the bottom of the port. A factory gasket was used and the squish unchanged at .021. Ports were widened to within about .050" of the skirt edges, and the transfers widened to within about .050" of the ring ends. The lower transfer ducts were tapered toward the base. The muffler mod only consists of removing the end of the cage and enlarging the factory opening as much as the deflector would cover.

Klotz R50 @ 32:1. 40:1 would be fine. 50:1 probably would be too, but I recommend 40:1 just for insurance on a ported saw.What oil did you use on that mix Brad?
Both intake and exhaust were widened to within 0.050" of the skirt ? Doesn't that increase the intake width by a larger % than the exhaust ? Just wondering if I should 1) make the intake as large as the skirt allows, as you did, or 2) widen the intake only the same % as the exhaust ?
Brad- the more they tear you down, the more you overcome. You are one hardworking, talented, and stubborn SOB
Same saw, same cylinder. The new owner didn't want it replaced and wanted it ported. I put about 1 1/2 tanks of fuel through it in 80° weather giving it very little time to cool between cuts. Even with the new piston, I spared it no mercy. If it was going to seize, I wanted to make it happen right now.
Brad don't worry about overheat, two corners missing aint no thing. If I posted a pic of a 371 cylinder I have here, that has been in service for a year in a landscape company, it would put all the nay sayers to rest! This time around its getting ported more and pop up time.
