Default Tutorial on CDI ignitions?

Mags aren't used often anymore on engines people rely on to run 24/7. Don't get me wrong, mags are fine and have their place if you want period correct but the truth is the quality of mag parts isn't a fraction of what it was 20-30 years ago. It just this simple, mags are not the best choice anymore. Like it or not the CDI ignitions are here to stay. So my question.

Would there be interest here in me doing a tutorial on how to install them?

The same principle as your lawn mower, no moving parts in it's self but uses the flywheel to generate the electricity.

I'm curious on how the magnet is placed and if it uses a module like a motorcycle or coil unit like Briggs can it be added to any flywheel engine and how do you find placement?

Look at an airplane, they run on two they use them because they are reliable.

At least in the day, airplanes used Bendix magnetos. They were/are very very good. The reason Bendix isn't used on most oil field engines was you could buy a FM mag for less than it cost to overhaul a Bendix. I'll put it this way, would you really want to fly in an airplane that used FM mags?

But they use 2 for redundancy, because sometimes they quit.......

Many planes today have 1 CDI and 1 mag.

OK, back to the OP. I'll show how to install a "601" ignition on either a Fairbanks Morse or an Arrow C series. The method used is the same for any other engine. This will probably end up on Youtube.

601 was the reference Fairbanks Morse gave it when they developed it if I have my facts straight. The first one I ever saw was about 30 yeas ago, it had a brain box about the size of the first solid state ignitions Ford used during the 70's. They were a flop. FM more or less forgot about the thing and later i years a company called Dynelco (sp?) took the design and because circuits had been reduced in size and improved in quality they started making the ignition and called it the Star Fire. Then came several others who did likewise calling it whatever but they all were and are still a 601 design. FM even re released the thing. Personally I use Arrow Engine's copy as it is as good a quality out there and the price is just as good or better.

There are several brands out there. I use the Arrow unit and an aftermarket stand.

Any thoughts on pilfering a starfire system out of an old lawnmower - could it be made to work? Might bring the cost down significantly if it's doable.
