New engine carb rebuilt just tuned.....filter? Fuel pump?
What exactly is happening? Maybe the timing is way off. Whoever did the work needs to double check everything they did. It can't hurt to check the fuel pressure and replace the fuel filter. Is the clutch or transmission slipping badly?
No the truck has been running fine for a year just started Not going up hills starts idles the up the hill and quits
Maybe there is dirt/water/rust in the fuel tank and when you go up hills it shifts and plugs up the fuel intake.
