I just bought this truck from my great uncle, who bought it brand new in '84. The truck is in excellent condition. He was getting too old to drive. My question is. The engine runs good at idle, but whne you go to accelerate it hesitates. Sometimes backfires. If you coax the gas pedal alittle harder it will kick down to second gear and accelerate great, lots of power. It is that inbetween range of normal driving where I notice the problem.
I have changed spark plug wires, cap and rotor, checked firing order, replaced PCV vlave, and checked for vaccum leaks. The engine has 40,000 miles on it and it a rebuilt motor. Truck never smokes or gives any sign of fatigue. I haven't checked the spark plugs yet. And the carburetor looks like it could use a rebuild.
What would cause the hesitation and backfire at medium throttle?
have the same problem?
