Started my new project today restoring an old atco kick start. It's got very good compression and fuel is getting to chamber. However have no spark so need to take flywheel off to check everything there. I managed to secure the flywheel and undo the end nut. However because new to this machine and set up, I went very gently but then it stopped. Not knowing what was the problem I reversed everything and put up this thread in hope of help and explanation.
