Help Please! I am having a real power problem, NO POWER on grades. I have rebuilt the engine and it runs good, sounds good, does not smoke but I have no power. I can not go but 10 to 15 mph on a 4% grade and I believe I should get better than that. I have new fuel and air filters. My manuel show the airbox pressure should be approx. 24 psi at full load, my airbox pressure is zero at idle and 14 psi at 1800 rpm. Does the pressure increase at full load? Any help will be greatly appreciated. |
