I've had one of the tiny HF ultrasonic cleaners for about 10 years.  Probably cleaned at least 100 carbs in it.  Works well.  The cycle timer is annoying.  IIRC, it shuts off after something like 2 minutes.  5 or 6 cycles gets everything good and hot, and usually is enough to shake loose the hidden crap in the carb.  The model I have is really too small, especially since I work on Tillotson HL carbs for my old saws quite a bit.  The fluid BARELY covers the carb body for those big 'uns.  I keep meaning to replace it with something bigger (either a used dental unit on CL or something from Amazon or eBay).  Low enough priority that thought and funds never get directed towards it however.  This is the first time I've thought about replacing my USC in many months...

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.
