Greg, Thank you. This means that I was wrong in squarely blaming a tiny little (barely visible) hole which I detected for the engine at times not being able to rev up beyond 2000 RMP. I simply thought the diaphragm kept the piston up for as long as the revs were higher and stayed there. My detective work is back to square one.
