Scintilla Magneto: Manual
Introduction When discussing the golden age of small engines, agricultural machinery, and vintage aviation, few names carry as much weight as Scintilla . Although the brand is often associated today with its Swiss-made power tool components (now part of Bosch), to engineers and collectors, "Scintilla" means one thing: high-precision magneto ignition systems.

Measure primary winding between the "kill" terminal and ground. If open, the coil is dead. Rewinding is possible but manual suggests sourcing a NOS (New Old Stock) coil. Introduction When discussing the golden age of small
With rotor installed at #1 firing position, the manual instructs to loosen the coil hold-down screws and slide the coil until a 0.004" feeler gauge fits between the rotor magnet and the coil pole. Tighten, then confirm points just begin to open at that rotor position. If open, the coil is dead
