Turn the drive shaft by hand. You should feel a distinct "snap" or resistance (the magnetic "E-gap"). If it spins freely with no resistance, the magnets may be weak or the bearings shot.
This is the moment of maximum magnetic stress, resulting in the strongest spark. scintilla magneto manual
Unlike modern electronic ignitions, a Scintilla magneto is a self-contained high-voltage generator. It doesn’t require a battery to operate; instead, it uses a rotating magnet to induce an electrical current in a primary coil. Turn the drive shaft by hand
Apply a microscopic amount of "cam grease" to the felt pad. If oil gets onto the breaker points, the magneto will fail. 6. Safety Warning: The "Hot" Magneto This is the moment of maximum magnetic stress,
Many vintage Scintillas feature oil cups. Use only a few drops of high-grade instrument oil every 100 hours of operation.
By following these manual basics, you ensure that your vintage machine fires on the first pull (or swing) every time.
The most common "manual" task is setting the point gap. This dictates the timing of the spark.
