The info I found for setting the timing says to remove all spark plugs except #1 and crank the engine over with the throttle blocked at WOT (max advance ) . The timing specified was 20 Deg BTDC . My timing was @ 20 Deg so I didn't change it . I tried checking the timing again with all plugs removed and read 23 Degrees probably due to the fact that the engine was now cranking faster . Its probably "6 of one , half dozen of another " but I'm just wondering what the difference is . Is it a safety thing with having the the plug wire you're attaching the timing light connected to solidly grounded ? Any body know for sure? Thanks in advance
