ok4450,
Well, if heavymetal tests the compression of a rotary like a piston engine with a tester that locks on max compression, he might get good compression on both rotors, but miss the fact that only 1 of 3 faces would have good compression. That is like having a V6 with 2 dead pistons. There are specialized procedures needed in this regard and a piston head would not have caught that error and continued working under the premiss that the engine has good compression. Rx forums would not be like Riceboy type import forums in this regard.
I have recommended a good place to start since it looks like heavymetal has reached the limits of the knowledge available here and has described symptoms that resemble those of a rotary engine nearing the end of it’s useful life.
