PerTronix CU-121 Details

For over thirty years, the Ignitor has proven itself in applications ranging from race cars to tractors. The Ignitor replaces breaker points and troublesome factory electronic ignitions with a dependable, self contained and maintenance free electronic ignition system. The Ignitor has been called the "stealth" ignition because of its quick installation and nearly undetectable presence under your distributor cap. There is no "black-box" to clutter the engine compartment. For optimal performance, use the Ignitor with Flame-Thrower 40,000 volt coils. Delivers twice the voltage to the spark plugs, increasing horsepower, fuel economy, and spark plug life. 2:1 improvement over "points" in current fall time for increased coil output. Rotating cobalt magnets trigger a Hall Effect integrated circuit. No points to burn, no moving parts to wear out. Epoxy molding makes our module impervious to dirt, oil, grease and moisture. Stable timing - no need for any adjustments. Will trigger most multi-spark CD ignitions. Legal in all 50 states and Canada.

Makes my Cushman run great!

I have an 1983 Cushman Truckster with an 18 HP OMC engine. The install was easy. However, I did have to drill out the lockdown screw hole. The distributor in my engine used a larger screw than the hole in the plate. It fired right up after installation and has never run this good. The instructions have a black and white photo and was hard to see what they were describing but was able to install with the written instructions. Took about 2 hours to install with running new wire protectors. Mine were falling apart when I pulled out the old wires.
