So they sound like they are wound pretty tight.   I am guessing around 18 to 20 thousand Rpm's.

There are two strokes and four strokes.

The two strokes are usually turning in excess of 20,000

Some of those engines will cross 30K RPM's.  Astounding for a reciprocating engine.
-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.

Thats so cool !!!!

I turn over 40,000 rpm sometimes with electric motors on RC stuff.

Most times its 30-35k

The four strokes are the kings of the pulling contests.

I could see why too
-Lekkys overheat very quickly
-Nitros and 2 smokes rely on RPM's, loose them just a little and the pull is over
