Greg,
A while back I bought a 20B, for a spare.  I was warned ahead of time
that it didn't have any compression and needed rebuilding.  I squirted
liberal amounts of ATF into each of the intakes, making sure I got it
to all 3 chambers.  I figured that the ATF would help soften the
carbon deposits on the rotors, making them easier to clean during
rebuild.  In the interim, I will crank it through a few times about
once a month and add some more ATF.  It now "puffs" like it should,
but maybe not as strong as a new engine, but it sounds healthy enough
to run.  I just assumed it was due to the fact that it had the help of
the ATF to get the apex seals to seal a little better.  Im still
planning on going through this engine some day, but I'm tempted to
hook it up on a test stand to see how it runs before tearing it down.
