Noticed today that the dizzy on my Viva engined pop doesn't have the vacuum cannister connected to manifold vacuum. I'm not sure of a good reason to do this for street driving, so am highly tempted to check the timing, hook it back up, and recheck. It runs a little rich anyway so I need to tweak the carb (Stromberg CD)
Do most people with rods run vacuum advance on the street? I'm far more at home with a Magneto on the strip.
