That might be a busted Woodruff key

Hi it sounds like your timing is out, so woodruff key seems possible, My mate had a moped that would run forwards or backwards, its a good party trick when done on purpose, but not good if it does it on its own.

thanks for the replies

just taken the flywheel case off and the flywheel is smooth no rock (would i be able to tell if the woodruff key was gone) thanks lee
