Hello all, I have been given an old Mercury outboard which I intend to use with my old rowing boat but I cannot get it to start. There is no spark, I have taken the flywheel off and there are magnets set into the flywheel and a coil. There are no contact points but there is an advance/retard lever. The coils check out ok. They have continuity. If I spin the flywheel what voltage should the magnet/coil generate as I am only getting millivolts. The magnets are not weak. It is a very old engine but not as old as myself as I stopped counting at 80 and at a guess I would say about 2 to 4 hp and is a two stroke. Thanking you all for your help in advance.
