Review on Enhanced Performance with the Electronic Transistorized Ignition Module Nova by Brandon Mcvey

Revainrating 5 out of 5

A really easy and reliable upgrade to ensure spark plugs.

I've recently started rebuilding a small 1953 REO 211-G engine. I disassembled most of the major components to inspect for damage and then cleaned them. The single-cylinder, manual-start, four-stroke engine had a capacitor-type starting system. Basically, a magnetic flywheel spins around a metal coil (magneto) and creates a charged magnetic field. The capacitor creates an increased voltage when the piston compresses the vaporized fuel in the valve chamber. The spark plug creates an arc in the gap between the electrodes, which ignites the fuel. Back to the review. The old engine sneezed, ran rough, and had a very weak spark plug. Rather than tweaking and/or diagnosing capacitor/coil issues, I decided to upgrade the starting system with an electronic ignition module. This simple but very reliable component replaces the capacitor (but not the coil). I just cut one wire from the cylindrical capacitor, solder the corresponding wire from the module and the other to ground. When I checked the spark plug for sparks, it had a bright, pulsing arc every time the flywheel made a full revolution! Nice. After the recovery phase is complete, I can attach the gas tank. I bought two of these modules to have as a spare for any other small motor projects I start.

Pros
  • High marks for support and durability from testers
Cons
  • Fits
