Good info there.  When I get around to rebuilding my 335XPT California it'll have a plug in place of the decomp valve, and the port in the cylinder for the valve trigger signal will be blocked off however.

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.
