Why is it always weird stuff that breaks?

[chris vickery]

95% of Ford flathead ignition problems usually come down to bad coils.
At least, that was always my experience and that of countless other flatly enthusiasts.
The usually scenario involves a vehicle which starts and runs great until it starts misfiring or otherwise running like a POS.
I’ve had guys argue with me black was white when I offered up the suggestion that the coil was to blame.
Doesn’t matter whether or not it is NOS, old or modern replacement. Once cooks get hot ignition will break down if it is compromised.
The worst ones are the divers helmet first series, as they sit right on the dizzy where it’s hot to start with.
I always changed over any ford flatty to the crab type to get the coil up and out of the way to keep it cool
