Yes, definitely keep your vacuum advance - a car driven on the street needs vacuum advance to handle high vacuum, light throttle driving.

I talked to my engine builder yesterday, and he said the same thing that was in the FBO article. The timing mark on that plug indicates too much timing, but then again I am running vacuum advance. I will clean up the plug and disconnect the vacuum advance for my trip to Pumpkinfest this weekend and read it again. I will continue running vacuum advance, but at this point I am working on getting the jetting and timing worked out before I pull the car apart for the winter and get the rad recored. I also bought a quick change secondary spring kit, so I can play with the secondary opening which currently seems very slow. I'm not thrilled about having to chase my overheating problem, but I love analyzing and resolving issues.
