DESCRIPTION

The Ignition Control system is used to regulate vacuum

advance of leading and trailing distributor systems. In addition,

this system helps reduce CO and HC emissions by aiding pellet

converter warm-up during cold engine starts.

System consists of leading and trailing components of the

distributor system, vacuum control solenoid valve and connecting

wiring and tubing.

OPERATION

The Ignition Control system operates when engine is cold and

running between 1000-1200 RPM and when engine is hot during quick

deceleration from 3000 RPM.
