Electronic Choke (eChoke

™

)

eChoke

™

is an integrated control system that checks ambient and engine temperatures and monitors engine speed.

This system is integrated through wiring to a master ignition/control module. Extended cranking (beyond 10 seconds)

is not necessary, nor will it improve engine starting.

Calculations and unique software routines developed speciﬁ cally for this Kohler engine operate a carburetor choke

lever through an assembly (bracket, linkage) to control a stepper motor. Power and ground are supplied to master

control and ignition module (Cylinder 2) which provides a signal for stepper motor by way of a control harness that is

routed through cylinder #2 bafﬂ e. An interconnection harness between two modules may exist (model dependent).

eChoke Components (Includes ignition due to integrated system)

● Master & slave ignition modules (with interface cables)

● Stepper motor

● Stepper motor bracket, linkage, and associated fasteners

● Wire harness (for power and ground)
