Actually, after thinking about it some more I think I should probably just get rid of the hole around idle anyway. I was thinking back to tuning the distributor on my 71 Vette and realized that you set base timing with the vacuum advance plugged, and base timing is usually around 12 degrees or so. However, when you plug the advance back in, you may end up around 20 again. This table isn't base timing, it's got the vacuum advance built in, so I should probably be around 20 degrees or so when idling. I may give that a try later today and see if it helps the slight stumble when slipping the clutch to take off. I'll have to readjust my throttle plates, and hopefully I've got enough left in them to close to pull the rpm back down.
