how about a little 036 with a 72cc top end?
it can be done.
the idea for this 'poor man's big bore' came from member 'russ61' in this thread: http://www.arboristsite.com/showthread.php?t=128234
i took his idea to mount a 038m p/c on a 036 and ran with it. 038 + 036 = 037
the case needs clearancing to allow the cylinder base to sit far enough toward the pto side. i used a carbide bit with a flat end and freehand milled the non-machined lump off the case. a steady hand is a must!!! i finished it off with a fine file.

here is how much you need to open the case up or the piston skirt @ bdc.
the two faint scratched lines are roughly where i wanna be.

the 038m cylinder is abit more portly than the 036. cylinder fins must be trimmed.
