I just finished putting the header on the 40. The truck was 80% desmoged when I got it, so I just finished it up. The only thing left was basically part of the EGR system. All the vacuum lines, ect had been pulled, and the associated vacuum ports on the carb were capped. I attached a diagram that has a number of things marked. My main question has to do with the two vacuum lines that run from the distributor and to the carb (the vacuum advance). I thought on my 60 the two vacuum advance lines were attached to the carb itself (possibly in port 1 and 2) and NOT to the air cleaner itself. Before I did the header, the truck had good power, but idled very rough, especially when it warmed up. I also recall at least one vacuum line going from 4 to somewhere on the carb (on my FJ60) and what is 5? So, please make comments on my diagram...anything at all that does or does NOT look right to you. Thanks !
