Hi Steve, Thanks for the info!  I'm planning on an induction redo this
winter and will look for suspect 'bolt holes'  I had not thought of that
possibility, but will check it.  Actually, I'm fairly satisfied with
1550-1600, but experimenter are never 'done'..:-)  800 is a new challenge!

Congratulations to Bernie! Be sure to clean/dry out the electrode and
insulator set deep inside of stock plugs.
Regards,Tommy (if it clears some, OVC005, going flying today)

Tommy,
I had similar issues to begin with, and after talking with Ed Anderson, he
steered me toward looking for an air leak.  I was certain that I didn't have
any air leak, but after searching around the engine, I found source of the
air.

It doesn't take very much air to make it run high RPM's.  My leak was a bolt
hole in the lower portion of the original intake manifold that I used when
fabricating the new intake.  The bolt hole went all the way into the intake
inlet, which was letting in the air.

Now it will idle down to well below 1000 RPMs.
