Remote Control Linkage
The throttle lever is provided with hole for optional cable
attachment. The following illustrations show installation example
for a solid wire cable and for a flexible, braided wire cable. If using
a flexible, braided wire cable, add a return spring as shown.
It is necessary to loosen the throttle lever friction nut when
operating the throttle with a remote-mounted control.
High Altitude Operation
The LPG fueled engine does not require any modifications for high-
altitude operation. However, performance and horse power will
decrease at high altitudes.

The power rating of the engine indicated in this document is the
net power output tested on a production engine for the engine
model and measured in accordance with SAE J1349 at
3,600 min
-1
(rpm) (Net Power) and at 2,500 min
-1
(rpm) (Max.
Net Torque). Mass production engines may vary from this value.
Actual power output for the engine installed in the final machine
will vary depending on numerous factors, including the operating
speed of the engine in application, environmental conditions,
maintenance, and other variables.
