Well, folks, it's alive!
Started it up this afternoon!
I have some carb issues... at first the fuel was squirting from the vent. Lowered the float and it stopped. Once I got it started and idling, it acts as if it runs out of fuel. Fires up fairly quickly. Then the same thing. Hesitation with throttle. Runs out of fuel.
I have a thought on this... the reference source on the fuel pump sees vacuum as well as boost. I think that under vacuum, it is not allowing the diaphragm to push the correct amount of fuel to the carb, running it low or out.
When I disconnected the source, the carb sprays fuel again. Perhaps now that the pressure is correct, the float is too high.
I will adjust the float again tomorrow and try again.

Small victories! It started!
