  1. Vacuum line diagram

    The hood sticker has faded long ago and I need to get some lines up instead of having a few capped. Was looking for a diagram for the 2.8 or better yet some pictures of the actual locations to point me in a quicker direction if anyone could provide any it would be appreciated.

    How would you wire up a tachometer?

    I figured I'd need one and never installed one before, so any help would be appreciated. Specifically, how would you wire it to your ignition coil negative wire if that's where it connects? and how does that look?

    Idle speed adjustment

    Was curious as I am pretty new to doing anything with carbs, but I was curious as my idle speed is set pretty high, at least around 2k revs. I was wondering if I can get a simple procedure explained to me to adjust it, with possibly any pictures that would be appreciated.
