Lots of 2-stroke engines have 2 rings.  I have some very old saws ('40s, 50's, and early 60's) that have 3 rings.  They're all compression rings, as there's no need for oil control rings on a 2-stroke of course.
-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.

Yes I made it on a CNC. Going to make a few more, just wanted to make sure it fit before I made scrap aluminum.

Ring drag is considered a parasitic lose on engines .One the other hand mutliple ringed pistons last almost forever as does the entire engine .

As an example some of the old John Deere and Caterpilar engines had 4 compression rings and two oil rings .They are still running after 50 60 70 years on the same rings .Not too fast or powerfull  just run forever .Old rock solid Evenrude and Johnson outboard boat motors are the same .About the only way to kill one is to straight gas it .

I bought a new 1956 Johnson 6hp and sold it two years ago to my BIL for what it cost new. Over the years, I had to put a water pump, two coils, couple sets of spark plugs, Umpteen shear pins, rewind spring, and gas tank on it. The power head was never apart. 55 years old.
