just an observation, i had a vacuum gauge hooked up to a carb spacer using 1/8" tube out of the spacer hooked to rubber hose about 3' long to the gauge so i could read it while driving, there was a slight restriction in the carb spacer as i hadn't drilled all the way through for the piece of tubing and i couldn't get a reading. had to open it up.

makes me wonder if all the tubing you guys are using is large enough.
