I ran the Solo, but not the Mac, did you run that stroked 661??? I've run Lee's Mac's, but my favorite is his Big Bore Dolmar (with a 088 Stihl piston)!!!
Hey, I'll be brand neutral … I like how my Asian saws ran!!! (especially that Cross 660) I think I finally figured this porting stuff frigured out … only problem is now I gotta rip a bunch of stuff down to get it in compliance! Can't have all these second rate saws!!!
3 - Asian Big Bore or Hybrids and 3 - 660s! The only good thing, in the process I will put the 066 jug on the 066 base and the Cross P+C on the Asian base! (they are the reverse at the moment)
Hopefully, when I get done, they will all run better!
