CARBURETOR ADJUSTMENTS
A WARNING
If any adjustments are made to the engine
while the engine is running (e.g., carbure¬
tor), disengage all clutches and blades.
Keep clear of all moving parts and be careful
of heated surfaces and mufflers.
A WARNING
To avoid injury or an accident, be sure the
brake pedal is in the locked position,
transmission is in neutral, and any equip¬
ment is disengaged before starting engine to
make carburetor adjustments.
A WARNING
Carbon monoxide fumes can be fatal! Do
not make any adjustments to the carburetor
in a confined area such as a storage build¬
ing. Move the tractor outside into the air.
■ ^NOTE
Carburetor adjustments should be made
only after the engine has warmed up.
This engine is equipped with a fixed main jet carbure¬
tor. (Refer to Figure 20.)
The carburetor is designed to deliver the correct fuel-
to-air mixture to the engine under all operating condi¬
tions. The main fuel jet is calibrated at the factory
and is not adjustable. The low idle fuel adjusting nee¬
dle is also set at the factory and normally does not
need adjustment.
If, however, the engine is hard-starting or runs
roughly or stalls at low idle speed, it may be neces¬
sary to adjust or service the carburetor.
Turning the low idle adjusting needle in (clockwise)
decreases the supply of fuel to the carburetor. This
gives a leaner fuel-to-air mixture. Turning the adjust¬
ing needle out (counterclockwise) increases the sup¬
ply of fuel to the carburetor. This gives a richer fuel-
to-air mixture. Setting the needle midway between
the lean and rich position will usually give the best
results.
NOTE
Engines operating at altitudes above approx¬
imately 1829 m (6000 ft) may require a spe¬
cial "high altitude" main jet.
