I just pressure wash the whole saw.It is truly a pain in the ass. Who in the hell wants to take the recoil cover off in order to blow out your air filter?

I got the 268 piston today, I would really appreciate any suggestions on how to bring the rpm up without losing torque. As it stands now with the 266 piston my numbers are:
Squish .022
Intake 83
Exhaust 100
Transfers 126
Thanks for the advice, I'm going to give it one more try and if it doesn't work out I'll just go back to a 372 piston. At least when someone is contemplating using the 266 or 268 piston they can see how it turned out for me.Toss the windowed pistons in the trash is how I gained torque back. I never liked them in a 372 style jug. Raising the transfers will help from where you’re at right now

If you take the skirts up flush with the lower entrance, is that enough?To take advantage of the windows you need to raise the lowers way up. If not you’re dead heading flow of the air right into the wall above the lower transfer openings. Think of the piston as a cup upside down in a pan of water.

I'm just trying to understand, so please don't take this as if I'm arguing. If the windows are covered by the cylinder wall and won't let air flow through them wouldn't the piston be acting like the non windowed 372 piston. I understand that the windows won't provide any gain in flow, I also don't see how there would be any loss of flow verses the 372 piston. The reason I'm trying the 266 and 268 piston so I could make a pop up to bump up compression.To take advantage of the windows you need to raise the lowers way up.

That's odd. Mine ran crazy good. Gasket deleted. About the same psi you have there and squish. HyWay top end. I didn't raise the lowers much at all, just mostly blended them in nice and smooth. I did open up the intake as much as it would go, and shaped the lip a bit to dump down into the chassis. I forget which carb this thing had. Exhaust super open, both at cylinder and muffler. Didn't touch the piston. Running fairly lean, but with 32:1 mix. I brought her down a few rpms after I heard how lean it was in the vid. In person the thing is so loud, it can be a bit difficult to tell. She is in freshly fallen(and tensioned) European Beech in the vid.
That saw is running good. I don't know what I'm doing wrong but another member was kind enough to help me out and hopefully with his help I can get this figured out. I know I'm going to be working on the port shape and opening up the muffler some more.
