Thanks for the continued input, every little bit helps. We checked out the ignitors and have good spray pattern and spark. We can visually see the indicator on the fuel cock opens and stays open during the start. I also get a small T-4 rise to about 100*C which, I think, tells me the ignitors are lighting up. I haven't been leaving the starter engaged long enough to activate the T-5 relay (~50 Seconds) and it continues to motor (Green light) until I go manually to OFF after approx 15-20 seconds. Normal light off should occur at about 3 to 4 seconds into the start sequence.
The book says to look at the idle jet valve in the fuel pump and after further study I see that the idle flow goes through the Governor to the slinger wheel. I guess that adds another possibility to the list.
I'll investigate the 4 way valve. Thanks again to all.
