The 372 definitely looks better than that 660, but that's not hard to do
Grind the ---- out of it. If it is your stuff do what you want. Goodness, not like your asking what oil to run.
And seriously not a single comment on the greasy cylinder, probably ran HR1 and stuff.

No, a faster unrestricted flow vs. a lesser flow from restrictions is the issue.
I'd be very interested to hear info on any experience you have with opening up lowers excessively. I can't find anything with any pics or other information other than the "guess this piston" thread Snelling started a while ago. He had good results with that saw. I don't know how long it held up, but I'm assuming it still cuts.
My next thought is to see if crankcase stuffer cups from the 576 will fit it.
Wow, just saw this thread, 5 pages already. But it's a good topic : porting, a different recipe than the "norm", a well respected saw... Popcorn!
I think a lot of people have doubts about methods that stray from the norm. Videos showing stock/modded would always help convince people.
Also, a 372xpw is 75cc, lots of torque, and a 24"-28" bar territory saw. If you only need a 20-24" bar get a 60cc saw. Cutting smaller wood like 18" pine will likely be more a factor of chain speed than torque. I think that could be one reason it smoked the 660. Got anything bigger to test that saw with?

I applaud what you're doing. For me, there's FAR more satisfaction in building your own saw. Anyone can buy one. Kudos for taking a stab at it. That's how all of us got started. You have to start somewhere.
As far as the windowed piston...The saw I did it on responded favorably, as documented in the thread I did...The one you mentioned earlier. I now get those kinds of gains without the windows. Perhaps I should go back in my personal saw and window the piston again and see how it goes. After all, it only costs <$50 for a new piston.
Why does it look like Terry is sitting in shorts with his cock out under the jug?
