just looked and noticed that the homie with a clutch isn't like a ryobi or mac with a clutch, it's just a fancier drive adapter nut... now here's the important question:

which should I go with:
A) 25cc, removed post in exhaust port, pinned bowman ring, mild porting (exhaust to 150*), piston and cylinder in good to excelent shape
B)30cc, mild porting (exhaust to 150*), more questionable internals, ring is currently stuck, but should be fixable, and there are marks on the cylinder wall and on piston, just from being used a LOT, the shaft on the trimmer was SHOT, would probably wake up with a new ring

I got to the point of getting the post out of the exhaust port before I realized this, was just getting ready to take measurements of the current exhaust port timing.

I guess I'll keep working on the 25 for now and get a ring coming for the 30, have it set up to swap the long block after a while...
