Pulled the timer (stock Ford) off the '23 today after it started dropping a cylinder or 2 at full retard. After removing the nut roller retaining nut I discovered the pin was not in place. However upon further investigation I found the 2 pictured items stuck in grease in the timer cover. My question is this the pin that drives the roller? If not does someone have a picture of what the pin looks like? Is this a hardened pin? Not sure where the spring came from but the roller spring is in tack. If needed I can make this pin in the shop. Im hoping this is the reason she went to missing.

The pin is not hardened, a nail would work. If yours is missing use the one you found. Not sure how a pin could fall out as the retaining cap covers it unless you are using the one for the Anderson timer which has a gap that goes around the base for the flapper.

Here is the pin:

After the pin goes in, this keeps it in:

Then this nut on the end of the cam shaft:

Get the nut TIGHT, it keeps the cap on which keeps the pin in place. (Don't ask how I know)

I think you found the cause of your miss!

Sorry I forgot to include a shot of the roller. Missing the timer cap might have been the problem.

I found that when my T was not running smoothly with power the first thing to check was the roller timer. Cleaning the timer usually fixed the situation. But there is a better way.

This recent thread has a lot on tuning coils:

This stuff can get complicated with electricity, electronics, different types of timers, and different ways of tuning coils. So many decisions and opinions! I encourage you to look into the I Timer. No maintenance, and installation is easy.

I don't think you can do better than an I Timer and correctly tuned coils.
