Here are some preliminary leak test results! Kawasaki FH381V AS29-R One cyclinder showing 38% at 70psi but I am having hard time keeping piston at TDC? I have top cover off so I can see that magnet is at coil, and I have wrench on flywheel nut trying to keep it from rotating. The compression was around 70psi. Am I doing something wrong? I will have to get hearing aid on to identify where air is coming since the noise is low. I listen at dip stick, the carb inlet and exhaust outlet.
