1. A method of slow starting a combustion engine with an air starting system having a source of pressurized air fluidly coupled to an air starter via a control valve, the method comprising:

  • supplying bursts of air from the pressure source to the air starter by reciprocating a piston of the control valve between an opened position and a closed position, with selective application of a pull force to the piston to counter, in combination with a push force applied to the piston by the pressurized air, a normally-closing biasing force acting on the piston.
