[T3] TWO Successful Repairs!!!

[Keith Park]

Yes, that was a problem too that took 20 years to figure out, it wasn’t a problem for 20 years but after all that time it reared its head again with hard warm starts
Due to high fuel pressure and Jim finally came up with the answer.  20 years to plug up the threads!

And we wouldn’t have figured this out without and EXTRA GAUGE  😊

Yes, absolutely, and it's only fair to point out that I might never have made it to this conclusion if it were not for the fuel pressure regulator that Keith sent me for a post mortem, after it started delivering fuel at higher and higher pressure. That was more than 20 years ago, and I found nothing obviously wrong with it when I cut it open.

It wasn't until years later that I realized that dependable pressure regulation depended on one side of that diaphram having a good vent to atmosphere. 
The adjusting screw threads were enough when those parts were new, but rust eventually clogs them up.

This could be an even bigger problem if you drive up or down large altitude changes.

In my case, the problem was excessive richness, but that wasn't immediately clear from the symptoms.
