OKAy everyone, please pitch in. 1979 2.6, Federal emissions, original carb. anyone have a vacuum hose diagram that's better than the sticker underhood? can you guys go confirm what the three ports on the side of the carb closest to the left fender are connected too? one of them passes air into the intake, so the lowest one is manifold vacuum. the other two do not pass any air, they sat with a vac pump on them for 20 minutes-no drop in suction, the needle never moved. I suspect that if they are supposed to be used at all then they were plugged up on purpose and I'll need to pull the carb. so if I can CONFIRM they are supposed ot be in use on this model and what they go too, I can confirm I need to pull the carb. PLEASe- no guessing, if you have a '79 like mine, please take a look and tell me what's up.
