Description
FEATURES
• Overhead valve arrangement enables high power, and low fuel and
oil consumption
• V-Twin, four stroke design
• Air-cooled and gasoline fueled
• The light weight and compact design makes it easy to install and
utilize for many applications.
• A steel crankshaft and high-load bearing offer durability
• Pressure lubrication system and large capacity air cleaner enhance
reliability of the engine.
• The combustion chamber shape, along with a tuned exhaust valve
system, enhance the low exhaust emission and provides high
torque at low speed.
Standard features include a fuel cut-of valve, a 12V-15 amp alternator
and a pulse-type fuel pump.
The fl ywheel-type governor gear provides constant operation at the
selected speed against load variations.
The carburetor is a down draft, fl oat controlled fuel system with a fi xed
main jet. A fuel cut-off valve is provided to secure engine shut-down
when the switch is turned off. Carburetors are calibrated for sure
starting, good acceleration, low fuel consumption and adequate power
output.
A throttle solenoid (optional) automatically senses when the engine
needs to run at full power and when it requires idle speed. The sole-
noid operates using a 15 second delay before dropping to idle.
