Are you sure it's not flooded?
-Aaron

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.

Have you taken the spark plug out and put it on top of the cylinder and then pulled it over to see the spark.
