The m4501 is a spring-and-flyweight mechanical assembly that retards ignition timing during engine cranking. This impulse coupling installs between the engine accessory drive and magneto on piston aircraft engines, briefly advancing timing to generate a strong spark at low cranking speeds. The internal flyweights snap the magneto back to normal timing once the engine reaches operating RPM.
Installation and timing must follow current engine and magneto maintenance manuals by qualified personnel. Essential for reliable cold-weather starting on general aviation aircraft.
