How could an AC motor do this?

I've bought direct from Grainger's and also from them on line. If you have plastic, they're fine with that. But many parts are available from multiple sources on line and if you're not desperate to have "it" that same day you can sometimes find a deal.

Correct!, There are many good sources online if you have the time to wait. I have also found Amazon to be a good source as well, especially for tools. I needed several metric taps over the years, and local sources suck hard, I found a few tools stores out of Texass that ship fast, good quality tools, they sell on Amazon, just like ebay.

Installed now. seems somewhat quieter, no "bumping noises" at startup. I put it back on "auto", so it will not run constantly anymore--BUT lowered the "cutoff temperature" of the blower switch--so it will run a bit longer, before shutting down after the burner does.

If all holds well--I will toss the old one in a few days. it is not really good for anything...BUT in an emergency, if this one dies of infant mortality--it WILL run once started by hand.
