Mitsubishi Mini Cab U42T 1997 model New plugs. New oil and oil filter I got it to quit overheating. Pulled radiator and flushed and new water and antifreeze. Dropped fuel tank and cleaned and emptied. New fuel and new fuel filter. This is the 2nd New fuel filter after draining tank. I got it idling perfect and runs smooth. As soon as I let off clutch barely it dies. I've checked vacuum lines and checked and checked. Everything is hooked up. It would at least drive before I started working on overheating problem. I have played with carb adj screws and it's no help. Please help. I cant figure it out.
