I have read all the manuals on the carb and it related items, but my question is do you have to have all the senors hooked up for the the carb to operate correctly? Can a person get any of the old senors (a.t.c. /air temperture control)? All of the vaccumn hoses have been removed. I would like to hook all the controls back up so the carb will warm up on its own. Does anybody know anyboby thats an old mechanic at a old datsun dealership? The truck runs good, but every once in a while it seems like it floods itself and then it is really hard to get it started. Thanks in advance for any help!  p.s. It's a 77 kingcab 620.
