Yes, that is the problem with mechanically generated spark ignition systems. Its a real problem with a lot of hit & miss engines. As the engine speeds up, the timing gets more retarded; not what you want. Ford knew that, so he allowed the driver to adjust the timing at any time. And drivers back the...

Yes, now I realize he is correct. I was thinking of my VW Beetle's flat four engine that doesnt have a 180° mark on its pulley.

Thanks for all your mostly encouraging comments. I use my timing light on my hit & miss engines to check when the ignitor or spark plug fires. It works with magneto, battery + coil and buzz coil systems. I’m just a hobbyist that came up with an idea that I thought might be helpful to the T community...

Thanks for your replies. As opposed to the ECCT, which I greatly admire, (albeit a bit expensive), my tester would show small differences in the timing output of the coils while they are actually operating from the magneto/timer in a running car. This would not only show differences in the coils the...

I have hit & miss engines, some of which use the Ford buzz coil for ignition. I have designed and built a LED timing light that runs on a 9V battery and has a clamp for the spark plug wire. The buzz coil produces a bunch of sparks when activated, but my design will only flash on the very first spark...
