Sure sounds like it's running too rich.

I switched to normal copper core plugs and the hot start problem went away
for at least 10 starts until I fouled the plugs, should have bought one step
hotter.  Platinum plugs are defiantly a problem in our cars, they foul
quickly. I have narrowed down the problem with my idle as a idle bleed
orifice problem.  I am not getting enough air into the idle circuit to run
the optimum fuel air ratio.  I have a idle bleed screw set ordered and
should be able to try it on Friday.
  Thanks for all your help, further developments to come.

Dear Richard,

Ah-ha! So that explains it. I always wondered why it was that such a hot
shot plug would specifically do so poorly in an ostentsibly normal engine.

Warmest regards, Chuck Engles
