I just got another spare
distributor and decided to remove its rotor button while I cleaned it's interior. Same deal again. no messing about this time. 300mm multi grips and still did not want to come off but I persuaded it and it came off. totally stuffed! Glad I have a new one. Mik, I weigh, in the old money, 320 pounds, or decimal 136 kilos. When I lean on something, it stays leaned on. lol
