I drove the car yesterday after installing the new anti-backfire valve that Quick Fuel sent me. Everything is great now and as it should be. The kit is different than what came with the carb. You drill out the hole bigger with the supplied drill bit with drill stop. The seat, ball, and spring are bigger. Possibly an improved design. I took pictures but for some reason I can't upload them, the button is not showing to upload.

Just to summarize this situation:
Quick Fuel left out the spring in the anti-backfire valve. Without the spring the vacuum sucks the ball down to the bottom of the hole and blocks off the vacuum port. No vacuum to the power valve and the power valve stays open. As soon as you get into the primary main metering circuit you will go rich. This was not easy to find and was confusing to say the least. It costs about $100 in jets, air bleeds and restrictor jets and two tanks of gas to get to the problem. About half the jets costs, I would have had to pay anyway to tune this due to altitude. I still really like this carb.

I just have some minor fine tuning to do. I put on the zip tie to try Patrickt's secondary opening check and do the adjustment.
