Remove the old points. Manual gives gap: 0.014" (new). Clean the cam felt wick with lighter fluid, then oil with one drop of cam oil (not motor oil).

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. scintilla magneto manual
Per manual, mark the magneto flange position relative to the engine case to preserve timing. Remove the two flange nuts.
If you have landed here searching for the , you are likely standing in a dusty workshop, staring at a rusty tractor, a vintage chainsaw, or a 1940s aircraft engine. You have a piece of history that won’t spark, and you need the sacred text—the service manual—to bring it back to life. Remove the old points
This article serves as a comprehensive resource. While we cannot host the copyrighted PDF here, we will provide a complete guide on how to find, interpret, and apply the information within a , including model identification, common failures, and step-by-step troubleshooting. A Brief History: Why Scintilla Matters Before diving into the manual, understanding the manufacturer is crucial. Scintilla AG was founded in Switzerland in 1917. They became world-renowned for their magneto ignition systems used on high-speed internal combustion engines. Unlike battery-coil systems that rely on a charged battery, magnetos generate their own power using permanent magnets and induction coils. This makes them reliable in remote locations—hence their use on farm tractors (Ford, Ferguson), military generators, and aircraft (such as the de Havilland Mosquito).
Your search for the manual will require patience. Check vintage tractor forums, sign up for email alerts on eBay, and ask local aviation mechanics. Once you have it, treat it as a museum piece—laminate the wiring diagram and keep the original safe from grease. | Series | Common Applications | Notes |
Remove the rotor (manual warns: do not hammer the shaft—use a puller engaging the internal threads). Set the rotor aside carefully—the magnets will attract metal debris.
