My old truck ran (rough) and drove until I had the carb rebuilt. I put it on and was trying to adjust it when all of a sudden I lost all ability to turn the engine. I went and had my starter rebuilt and still no turnin over. I believe the bendix is engaging the flywheel, just not turning over the motor. New battery, same results.... I finally got under it and put the screwdriver to the flywheel. It turns freely counterclockwise but hits a stopping point going clockwise. Is that real bad news ?
