1986 Chevy Truck 6 cyl Two Wheel Drive Automatic
1986 Chevy C/10, With a 1971 fresh rebuilt 250 cubic inch Inline 6. Ran for four months fine. Now has major lack of horsepower only when in gear. Idles fine in park, Revs nicely to the max and responsive. But in gear it wants to die, Back fires and lacks power. The usual suspects have been dealt with. A know good working single barrel carb installed, a know working distrubitor installed, new points, new condenser, new plug wires, new coil, new spark plugs, The push rods are dead straight. Fuel pump is good, Even the fuel has been checked for water or dirt. Still not working well. I am thinking electiral however mabye a bad valve or bad lifter, but the Head is new. Totally stumped on this one.
have the same problem?
