If the factory engineers were so perfect:

a) where are they now? Oh yes, out of business.

b) why were there service bulletins, like rerouting the vaccuum pump exit into the manifold because it caused rough idling with the wipers in use? Could it be a minor design issue could be improved here or there? Or other changes discovered AFTER they went out of business so we couldn't get the gospel from them on packard letterhead?

C) Why were there SO many running changes to the ultramatic?


Obviously, in any make, "from the factory" isn't perfect, expecially after so many years.

I DON'T THINK CLOTHES PINS WORK EXCEPT FOR BEING PIECE OF WOOD TO SEPARATE WIRES FOR ONE TEST I CONSIDERED USING IT FOR. GET OFF MY BACK.

However, so many people believe in it, it bears testing to see if it does have some grain of truth, and like bigkev said, if it does, find out why.
