You need to clean the points with a piece of 320 wet or dry until they're shiny. If they're pitted replace them and set the gap at .013".

An easy way to keep the mag in time is to note where the rotor is pointing before you pull the mag. It's best to make a little sketch, THEN DON'T MOVE THE ENGINE. To reinstall the mag just put the rotor in the postition shown in your sketch. The applies to a distributor too. Your coil may be ok and if the magnets are weak you won't have any spark or a very weak spark since the magnets are what creates the fire in a mag as they pass by the coil. You can check them for magnetism by touching them with a flatblade screwdriver. They should attract that screwdriver
with a lot of effort. Here's a mag off an old twin cylinder garden tractor with weak magnets.
