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!!
