The Kelly ES3007 Impulse Coupling Assembly is a precision ignition system component designed for use with compatible Slick magnetos on aircraft piston engines. The impulse coupling provides the necessary mechanical action to increase magneto rotational speed during engine cranking, allowing the magneto to generate a stronger ignition spark for reliable engine starting.

The assembly incorporates a spring-loaded coupling mechanism that temporarily stores rotational energy and releases it at the correct ignition timing point. This action improves starting performance by providing a hotter spark at low engine RPM while also helping ensure proper ignition timing during the start sequence.

Manufactured for aviation ignition system applications, the ES3007 impulse coupling assembly is intended for magneto maintenance, overhaul, or replacement procedures when inspection identifies wear, damage, or reduced performance. Proper operation of the impulse coupling is essential for dependable engine starting and overall ignition system reliability.
