[700rpm]

Good suggestions, gentlemen.
30 coupe: it rocks back when cold. I haven't tried that when it is warmed up.
Jackson: all connections have ben cleaned and tightened. Cable may be bad. I'll check that.
James: I have replaced the starter with a known good one.
Benson: I can turn it about 1/2 turn.
40: there was less than minute between shutdown and plug removal.
Pat: see answer to James above.

I won't be able to work on it again till about Friday. I'll update then.
