The question was introduced , when to "tune" up the ignition tremble coils.

Reviewing the period literature, there appears to be no schedule in testing or adjusting. Yet conventional coil and points automobiles of a later period suggest every 12K to 15 K.

The only time attention is mention for attention to the timer is a few drops of oil every 500 miles.

Based on that bit of information the ignition - coil and sparking plugs - need to be attended to would be about the same period between 500 to 1000 miles.

Also it was suggested in the time and materials schedule, for adjusting coils, replacing point, and HCCT time should cost the customer $.20 per coil.

So it goes back to to the Ford dealerships.
Did they have any scheduling advice for new T owners other than having an owners manual?
Surely coil issues and missing were issues that occurred that the T owners would have to take their cars back in for service. Maybe it was just when it needs it or??

When your car runs out of the warranty, You may have to pay a little bit more for parts and labor.

If you have the original type timer, a bit of oil should be used. Some of the other timers use a special conductive grease or nothing. Depends on which timer you are using. As for the coils. If it ain't broke, don't fix. If it misfires you can substitute known good coils to see if that improves the situation or swap them from one position to another and see if the misfire follows the coil or stays on the same cylinder.
If you need to tune the coils, follow the instruction in the club booklet,"Electrical System". or send to someone who has the knowledge and equipment to do a good job.

Many service checks were suggested for Spring & Fall.

Original type timers require frequent oiling for lubrication and to prevent gumming.

It's best not to run coils until they are so badly out of adjustment or in need of points cleaned or other service that they cause misfires.


Coils that are getting out of adjustment, besides causing performance issues, will cause points and timers to wear more rapidly.

For maximum accelleration, higher top speeds, and maximum gas economy, plus easiest starting, keep the coils in good adjustment. Properly adjusted coils facilitate easy starting, good driveability, good gas mileage, and maximum timer and ignition point life.

PS: The sweating polar bears will thank you, as will Mother Gaia. Your car will produce minimum emissions when running with with well-tuned coils.
