Scintilla Magneto Manual (2024)
Scintilla magnetos utilize a or inductor-type design, making them smaller and lighter than older horseshoe-magnet models.
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.

Should read high resistance, typically between 8,000 and 15,000 Ohms (8kΩ to 15kΩ). Readings outside this window indicate internal breakdown of the insulation layer. Condenser/Capacitor Testing

Connect the high-tension leads to a calibrated 4-way or 6-way variable spark gap rack. Set the test gap to 7 millimeters (0.27 inches).
Ensure you find the manual specific to your model (e.g., Vertex, SF9, SB9), as internal components differ significantly between types. Conclusion
With the rotor locked or held precisely at the E-Gap position, the breaker points should just begin to open.
Rotate the magneto at 150 RPM (simulating engine cranking speed). The unit must produce a steady, bright blue, audible spark across all gaps.
