i dont know if this questio has already been asked, i didnt feel like searching through 23 pages of topics so im going to ask it. i have a close to stock 74 fj40 w/ 2f engine, every time igo up a steep hill the engine shuts off, it just dies no matter how much gas i give it, someone said there is a problem with the carb but iv rebuilt it and nothing changed. what is causing my engine to shut down?
