Well, I think they started to put oil in the overflow and stopped.  I
drained it all out, cleaned and refilled. Ran fine for a couple of weeks. I
don't think this is related, though.  Strapped the Hall on tight with a zip
strip and reinstalled last nite and started right up.  Will drive a little
later and see if it helped. Then get the right part for a permanent fix.
Will let you know.
