I have a clicking/knocking noise two times on each revolution with the crank. The crank resistance seems normal with the plugs out. I have every thing out from the oil pump to the distributer. The noise sounds like an impulse coupling releasing on engines that have a magneto. The clicks take place when the crank is at the 6 and 12:00 o'clock position the way I have the crank inserted now. What to look for?
