Mark Rocky Mountain,

Disconnect the manifold tubes.
Set all the table settings up a couple of number from what they are now
and try it again. Keeping doing that until it runs well at max static RPM.

The computer will think the throttle is wide open all the
time. So the top numbers are probably the most important.
You can try doing it to just the top table numbers first.
Those should be all the computer is looking at because
it thinks the throttle is wide open.

I forgot to mention. Put the mixture control knob
in the full rich position when you do this as the engine
will be two rich at half throttle setting and below and you
will then have to lean it manually. Report back :)
