A starting system for a manual only pull start internal combustion engine with a starting pulley, a pull cord wrapped around the starting pulley, a rotor selectively engageable with the starting pulley, and an ignition module located adjacent to rotor. The starting pulley has a pull cord groove with an enlarged diameter between about 2.5 to 3.4 inches. The ignition module is adapted to fire a spark plug of the engine with a timing retard of about 8 degrees at a speed of about 500 rpm of the rotor.
