This engine is mechanically sound,compression all good, It runs rough at all speeds and sometimes stall at idle. Timing at idle is sometimes 2-4 btdc and other times 2-4 atdc and others 7btdc. It doesnt jump around while running. It seems to change randomly when shut off and restarted as does...
This engine starts right up but runs rough at idle and no power, I have been diagnosing intermittent random loss of spark. I attached digital timing light to #1 and get steady 2* BTDC at idle, It then may lose spark to #1 so move timing lead to #2 and have spark working there as well as #4 and 6...
