Yes, I realize anyone that was racing threw this vacuum stuff in the garbage back then but I enjoy being frustrated by this quirky setup. It is working really well now so I can't wait to see what kind of times it will run. It is all you can do to shift it now with 3 carbs instead of 1. I was barely getting into 4th gear at the Meltdown with a 4:11. I knew something wasn't right and should have figured it out at the track but we were too busy replacing axles.
