Al,
It sounds like you have one of your Primary injectors
sticking or stuck closed.
After sitting for a long time I had both Primary injectors
stick closed.
The engine would start and run as long as the cold start was
on.
As soon as the cold start was turned off it would die.
Test each injector statically to see if it clicks when power
is applied.

I'll probably go ahead and do the test, but I don't think that's it.  When I
turn the secondary off the mixture is too rich. I have to lean quite a bit,
and then as the mixture bar gets about mid-scale, it begins to act like it's
too lean - some surging or whatever.  Just kind of strange.

Thanks,
Al
