If you don’t have a tool to align the coils, they can be set with a straight edge. The coils sit on little towers, two per coil and the outer edge of the coil must be in line with the machined area on the towers or else they will rub on the flywheel. It’s a pretty tight fit in there so alignment is critical to help get a hot spark. You will also want to clean all of that metal powder out of the magneto before trying to start it.
