November 7, 20232 yr You take the plug out and kick the engine over. There is a spark. You replace the plug and kick it over repeatedly, but it won't run: Look at the green ignition wire very carefully. It connects to a small bolt on the points via a small brass fork terminal. If that fork terminal is not fitted squarely onto the points connector, then it may/will arc across to the ignition carry plate, or even to the points cover when the spark plug is under compression, in the engine. If the fork terminal is placed on the outside, under the bolt's head, then it WILL arc across to the points cover, when under compression. Put the bike in a dark place - shed or garage. Turn the lights off. Take the ignition cover off. Get someone to kick the engine over while you look closely at the points. The point's contacts may/may not/sometimes spark. Disregard that. See if you can spot a spark elsewhere. That will be your problem.
