<VV> Maybe the starter.

I am surprised that more of you haven’t experienced the worn bushings and dragging starter syndrome.  As stated by others the bushings wear to one side due to the load of cranking against the starter/ring, gear the same direction all the time.  At this point I realize I am going to run afoul with those that believe a cool engine cranks harder  than a hot one.  In a hot engine the parts have grown to their maximum dimension.  Pistons are bigger, rings have grown in length.  Everything in well lubed and oil has closed tolerances .  In the starter the armature moves sideways into the worn area of the bushings.  It starts to turn and runs into the marginally heavier load of the hot engine.  Due to the worn bushings it is running closer to the field.  It starts drawing a ton of current from what is a normally well charged battery.  More magnetism than normal which snatches the armature solid sideways against the field coil. It’s not going to turn till the key is released or the battery goes dead.
I request that if anybody wants to challenge this that they pull their starter and look at the drag marks on the field cores and/or armature cores where they have been rubbing together.
This is not to say that a bad solenoid ,corroded battery clamp, or other connection can’t exhibit similar side effects   Smitty
