I just bought an 85 F150 with the inline 6 and having trouble with the carb. I have never really messed with a carb before and cannot figure mine out. The guy i bought it from put a remaned carb on it but i dont know if everything is hooked up right. I am assuming its a feedback carb since it has the emissions stuff, here are a few things i noticed may not be right.

Where the gas line goes into the carb, to the right there is a capped off port.
There is something not plugged up on the right of the carb that may have something to do with the feedback i dont know, its 2 black wires coming off the bottom

I will try and upload some pics to help with
any advice on what i should do or maybe where i can get wiring/vacuum diagrams would be appreciated
