When four runners are not like the others
On my Weber intake there are four runners that have been piped underneath to accomodate a vaccum source. Because of the added air should those four have bigger idle jets? I currently have 75F10 all the way around. I recently had to jump up to 75's because I added stack screens to the equation. Maybe 80's on the odd four?

I would say NO! Since the vacuum outlet is not as such an air leak, the vacuum measured at each runner would no doubt still all be the same. The answer wold be to measure the vacuum signal at each intake.

I'd say no too, but measure to be sure.
Why not plug'em or drill for the other 4?

Well I need them for the vacuum for the car right now.. I have conisdered getting an electric vaccuum system for the car and them plugging it off. I may yet. I am just not ambitious enough lately to run to the other 4.

I'd be plumbing a vacuum take off from ALL 8 runners or plugging the existing and running an electric vacuum pump.
All 8 plumbed together with 3/16 line doesn't really affect idle tuning that much.
