Lynn, et al,

Finally getting a chance to look at the engine closer.  The oil jets are
clean for both rotors, so there goes that theory - maybe.

Can you tell me if I made a mistake  when I took out the ball and spring
valves below the jets and drilled them out to 5/64.  (This engine was put
together in the last century by a younger me.)

Also, careful pre-assembly of the bypass valve assembly and front shaft
components shows that the bypass hole is only slightly over 1/2 blocked.
Should this not be completely shut off?  Perhaps the pressure that should be
cooling the rotors is just not available?

I am going back in with Tracy's overhaul kit, and it appears that includes a
new thermal pellet plug, so I will check the opening again with the new
plug.  I suspect my home-made unit was just installed on faith using
measurements from who-knows-where.

I will post any further findings as they occur!!   All ideas gladly
considered!!
