Re: Coil rebuild
Capacitor leakage does not degrade coil performance significantly unless it's very bad. I would not replace capacitors if the VALUE measures 0.47uF +/- 20% ( or 0.33uf to 0.56uF). Capacitors with lower value should be replaced in my experience.

3D Analysis of the Ford T Video
Interesting 3D video model of the Model T engine and plenty of details to take issue with including improper cranking, rated HP, etc, etc. Perhaps some constructive feedback can help refine the video to improve its educational value.

Repaired a tiny hole in my vaporizer carburetor float.

Granted, it did take a couple of months to fill u...

Re: How long can the T run on battery ignition ?
It also depends upon what type of ignition you are running. The E-Timer electronic timer operates much more efficiently than a stock timer, only firing the first spark with the full energy to ensure complete combustion. All subsequent sparks fired while the timer is "on contact" are strictly cosmeti...

Arnie, that is correct; a Model T coil should never be operated without a suitable spark gap. The coil spark gap should not exceed 1/4" at ambient atmospheric pressure. The concern with wider spark gaps is the coil will spark internally to the coil winding causing a breakdown of insulation and possi...

Re: What gauge wire to Buzz coils?
