starter failing to disengage?
This is an open response to Sergey Vushakov, who asked me what the eventual solution to this problem was--
The problem went away when we replaced the vacuum pump.
We did not realize it was going out until one day we were going down the freeway and suddenly the power brakes got hard and the engine refused to shut off. The vacuum pump was found to have worn internal seals.
Once we rebuilt the vacuum pump, the problem went away, and to be honest, I had forgotten to supply these results to the forum.
I'm not sure why this worked, so--Does this make sense to anyone? BTW the starter, solenoid and bendix drive have not been touched and have given excellent service down to this day.
