Nice rig. I just may have a wiring diagram but will have to look tonight. I drove mine threw Lincoln just a couple weeks ago. The miss in mine isn't accelerator pump. You can be on a steady cruise and as you start a hill it will surge. Pretty sure its lean but why is the question and a vacuum leak is possible but i don't hear one. I'll dig into it tonight. By the way are you still involved in circle track? This picture is a former life for me.
