Okay, Tom.

Saw something very interesting: flushing the distributor using a separate tank filled with carb cleaner and A.T.F. because of sitting. Thought that had validity and be sure nothing was sticking before tearing apart and finding nothing wrong. What do you think?

A:

Perhaps you could alert all of us as to the source of what you "saw", so that no one will ever rely on that source.

Bringing a strong, non-petroleum based solvent into contact with the diaphragms in the fuel distributor is a spectacularly bad idea.
The solvents in "carb cleaners" are intended for metal cleaning, and will attack any rubber, whether natural or synthetic.
A more appropriate solvent would be kerosene, or "paint thinner/mineral spirits".

Mr. Reiner, thank you so very much for the help!

It was the Source, but on a 6,3, so maybe different.

Brake cleaner fall into that also, right? I keep that way from rubber just based on what it does to my skin (you try and avoid, but still happens).

Or diesel oil, right? Kerosene is #1 diesel, thus my thought of why.
