The last couple of trips I have been on my 77 bronco starts dying on the trails after it gets hot. I was at Flat Nasty last weekend and by the end of the day Saturday it was daying constantly when I was at an idle speed on the trails. I have tried adjusting the screws on the carb ( stock 2 barrell motorcraft), I did get it to run pretty smooth, but I did notice that one of the screws would kill the engine when I had it all of the way in, but the other one would not. I don't know if this is right or not? The other thing that has changed is that when I bought it last October when ever I would start it the automatic choke would bump up the idle and I could bump it back down with the gas pedal. The choke no longer seems to be working. It is also hard to start when it is hot, but you barley have to touch the key when it is cold to start it. Any idea what I should look at first? I am not sure where to start. Oh, when it is "hot" my gauge reads around 190.
