ENGINE PRINCIPLES AND OPERATING REQUIREMENTS
An engine needs three basics to run properly:
Correct air/fuel mixture
Compression
Engine
runs
A spark at the right time
If one basic requirement is missing the engine will not run.
STARTING THE ENGINE
When experiencing engine-starting troubles, it is easy to work out of sequence and forget basic
starting procedures. The following sections describe the recommended starting procedures.
Engine is cold
1. Shift the transmission into neutral.
2. Turn the fuel valve on or confirm if the fuel is in upper or below retile in the fuel tank.
3. If the air temperature is below 0
℃
（
32°F
）：
Open the throttle two or three time to allow the acceleration pump to feed additional fuel to the
engine.
If the air temperature is below 35
℃
(95
℃
) pull the choke knob all the way out to richen the
air/fuel mixture.
4. When the engine starts, allow it to idle for approximately one minute, then push the choke all the
way in. If the idle is smooth, use the throttle to keep the engine running until it warms up.
NOTE
Do not race the engine during the warm\up
period. The carburetor accelerator pump can
overly richen the air/fuel mixture, which would
cause the engine to stall.
Engine is warm
1. Shift the transmission into neutral.
2. Confirm if the fuel is in upper or below retied in the tank.
3. Release the hot start lever as soon as the engine starts.
