J.Walker sent me his 238SE with a stock 242XP top end. It ran real well turning 15,500 WOT. I ported the piston and cylinder, reduced the squish, modded the muffler, installed a 242XP carb, and put it back together. It ran good before but just didn't have the "grunt" I like in a saw. That's not the case now! It's now turning 17,000 RPMs and has tons of torque in the cut. I suspect this little bugger will handle a 8-pin .325 sprocket well, but I don't have the tool for this clutch here.
The baseline and initial ported cuts were made with a sharp Carlton chisel chain. I'm less than impressed. I then switched it out for a brand new out of the box Stihl RSC. Wow, what a difference. Tonight I'll be square grinding this chain to see what else can be had.
