3.5 Gaseous Fuel System
The gaseous fuel system utilizes a fuel valve (with
solenoid) to control the fuel flow to the fuel regulator.
The
generator-mounted regulator reduces fuel
pressure as fuel passes to the carburetor. See
Figure 3-4. The carburetor controls the ratio of fuel to air
under varying loads and speed conditions. Because the
carburetor receives fuel in a gaseous state, it does not
have to provide vaporization of the fuel.

engine. No adjustments can be made. Contact an
authorized service distributor/dealer about adjustments
for altitude performance on emission certified engines.
3.6 Air Cleaner
At the interval specified in the service schedule, inspect,
clean,
or replace the air cleaner element. Clean the
element more frequently in dirty, dusty conditions.
Check the element for accumulated oil or dirt that could
cause poor performance.
Replace a damaged air
cleaner element. Follow the procedure described
below.
Air Cleaner Service Procedure
A dry-type air cleaner silences and filters the intake air.
The air intake silencer assembly connects to the intake
manifold via a flexible hose. Refer to Figure 3-5 during
this procedure.
1. Release the spring clips to open the housing and
remove the air silencer element.
2. Tap the element lightly against a flat surface to
dislodge loose surface dirt. Do not clean the
element in any liquid or use compressed air as
these will damage the filter element.
3. Examine the element and housing for damage.
Replace the element or housing if necessary.
4. Wipe the cover and base with a clean rag to remove
dirt. Make sure the sealing surfaces fit correctly
and reattach the spring clips.
