How to tune ThermoQuad secondaries?

Thanks for the tip but I took that carb off months ago, it just turned out to be way off in pretty much every aspect... My MPG went up by 3 just swapping to a known-working AFB even when I was taking advantage of the working secondaries :evil4:

If/when I do try another ThermoQuad I'm going to get a core that's set up as close as possible to my engine combo from the factory and have it tuned by DemonSizzler from there if it doesn't run well. I just gotta see it professionally done before I can figure it out myself. I think my cousin is actually wanting to get one for his 440 Polara to improve gas mileage so we'll see.
