Hello everyone,
So my dad and I have been repairing his 1971 mach 1 mustang 351C 2V that he had in high school and college until it broke down. It's just sat for 30+ years until this past summer when we sent it out to a shop in town to get it to start, run, and stop. While they did manage to do that, they didn't do the best job in the world so for the past couple months, whenever I'm home from college, he and I always work on it together and I've gotten almost everything running beautifully now except for one big problem we have. The carburetor coughs. So when it's idleing in park it's just fine and in drive it's perfect too, but when driving it, when you step on the gas too quick the engine will "cough" out of the carburetor. I can't seem to find anywhere where someone's got the problem figured out. Some people say the fuel mixture is too lean, but when you accelerate in park it's fine so I didn't think that was the problem. Others say the Carb is just old and needs to be replaced or rebuilt, and others say it's the fuel pump itself. Honestly we're both lost on this one so if anyone has a list of things to try to identify the problem and try to fix it that would be a lifesaver. Thank you so much.
