Speed Control Assurance Operation

Auxiliary Kill
Switch Contacts
Ignition Primary
Engine Ground
The speed control assurance consists of two series connected switches. If one or both switch plungers are posi-
tioned inward, the circuit is open and the engine will run.
At idle, with the throttle lever properly adjusted, the bottom switch circuit is open and the plunger is inward. The
top switch circuit is closed, and the plunger is outward. The speed control circuit is open, allowing the engine to
run.
As the throttle lever is actuated to an off idle position, the top switch circuit is opened (plunger in) and the bottom
switch circuit is closed (plunger out). The speed control circuit is still open, allowing the engine to run.
In the event the carburetor or controls malfunction and allow the throttle cable to become slack, the circuit will
close (both switch plungers out), grounding the ignition system and causing the engine to stop.

Speed Control Assurance Adjustment

Throttle lever free play must always provide a specified
clearance between throttle lever (A) and throttle block (B).
This clearance is controlled by the throttle cable sleeve(s)
and the idle speed screw(s).
Throttle Lever Freeplay -
Regular Throttle - .010 - .030 (.25 - .8 mm)
If the idle speed screw(s) is adjusted inward and the cable
sleeve(s) is not adjusted to take up the throttle lever to
throttle block clearance, the engine may misfire or kill upon
initial throttle opening.
CAUTION:
After any idle speed adjustments are made, the throttle lever to throttle block clearance and oil pump adjustment
must be checked and adjusted.
NOTE: When adjustments are made on models which have more than one carburetor, refer to Section 6, Car-
buretion, for proper carburetor synchronization adjustments.
