Aaron I couldnt imagine a muffler modded 335 hanging with a 200 with just the spark screen pulled. Still interested in knowing test results.

Back up just caught a wording. Is your 335 a California Special 45cc  ?  OK that could be very interesting.   :P 8)

Yessir it is.  Finally got it from my friend Dave (he brought it disassembled in a box as a Christmas gift........ugh).  Looks like the cylinder will clean up.  Just some transfer.  Have located a new OEM piston/ring for it (43mm).  The 'regular' 335/338 pistons are easy to find.  The 43mm took a tad more searching...

For older saws:
Tune the H side so that it 4-strokes (burbles) at WOT unloaded and just cleans up when under load.
When you lift cutting load, the saw should immediately revert to 4-stroking.  Fine tune the transition point for the wood you're cutting.
