[R-390] Ultrasonic cleaning

[rbethman]

I ran 4 stroke Enyas, Saitos, OS 4 strokes, including the 120 Surpass 
with fuel pump.

Never had any issues with any of them.  I even had an OS FT-240 that ran 
wonderfully!

I preferred 4 strokes over two strokes after my initial period flying 
the 2 strokers.

They perform very well!  I sort of miss it now.

But I sort of lost interest when I lost my FAA medical and couldn't sit 
in the cockpit any longer.

The best times in the cockpit were always flying aerobatics.  Have flown 
a Super Decathlon, Sukhoi SU-29, and a clipped wing Taylorcraft.

I just lost the desire since I couldn't go out and fly the real deal any 
longer.
