Okay so I bought a 82 f100 with a 302 in it to drive to class and back and it's having major issues. I don't really understand carbs or how to diagnose the issue so I'm hoping someone here can help. Whenever I go to accelerate or slow down while driving my engine tries to stall out. I have tried running carb cleaner through the ports in the carb, I have tried using seafoam and cleaning jot the vacume lines, I have tried using the spring kit and swapping out the springs. I don't know what else to do. I swapped it to a normal colored spring and it worked a lot better but it still had alittle bit of the issue so I when to go down a spring. Whenever I did I realized I didn't hook a specific hose up so I did and the issue when back to being terrible. I don't know what this hose does so I included a picture in the post so maybe someone can tell me if I can just leave it unhooked please I don't know what else to do and I need the truck to be able to get to school. I payed for this truck with my money from working. I can afford to take it to some shop so they can charge a ton to get it fixed. The hose I was talkin about is the black one next to the black cap.
