What is the best way of finding TDC on my O-320? From what I gather, place your thumb over the spark plug hole and feel for pressure build-up. This would be the compression stage, them introduce about 20 psi of air into that cylinder and rotate the prop slowly (in normal rotation direction) until I feel a "flat-spot" or no resistance, that would be TDC? I was also told I would hear a loud click. is this correct?
