Apply a single drop of clean, lightweight engine oil or specialized magneto lubricant to the felt cam wiper pad. The pad should feel damp to the touch, never saturated or dripping.

Opening the points instantly breaks the primary circuit. The capacitor absorbs the inductive kick to prevent arcing across the points. This causes the primary magnetic field to collapse instantly. scintilla magneto manual

The Complete Scintilla Magneto Manual: Operation, Maintenance, and Troubleshooting The most critical adjustment on a Scintilla magneto

A magneto is a self-contained high-voltage generator. Unlike a battery-and-coil system, a magneto requires no external battery. It uses permanent magnets and a induction coil to create a spark exactly when the piston reaches compression.

An excellent resource for technical manuals, especially for WWII-era Bendix-Scintilla aircraft magnetos. Opening the points instantly breaks the primary circuit

Always treat any engine equipped with a Scintilla magneto as "live" until you have visually confirmed that the P-lead grounding wire is intact, structurally secure, and properly bonded to a verified chassis ground. When performing internal adjustments or timing procedures on the bench or in the chassis, always disconnect the high-tension spark plug leads first.
