Kawasaki FC290V Carburetor - Cleaning and
check
Do not clean jet orifices with hard object. Dip carburetor components
except non-metaric parts such as gasket into carburetor cleaner until
dirt is removed and rinse them with solvent. Rinse carburetor aluminum
components in hot water to neutralize corrosive action of cleaner, if so
instructed by the manufacturer.
Dry components with compressed air. Make sure all orifices and passages
are free from dirt or foreign object. Do not use rags or paper to dry
components to avoid plugging orifices by lint. Check diaphragm for
crack, tear, or pin hole. If defect is found, replace it.
Kawasaki FC290V carburetor adjustment
Float adjustment
Do not strike float pin to remove or install it, to avoid breakage of
pin holder. To remove float pin, pull the transformed end with pliers.
To install float pin, push float pin transformed end until the other end
flushes with pin holder outer surface. Do not push down float or needle
valve when checking parallelism.
Check float angle and correct it as follows. Place carburetor upside
down and check whether float surface (A) is parallel with carb. body (B)
when float tang (C) just begins to come in contact with point of needle
valve (F). If not parallel, adjust float surface angle bending tang (C)
with needle-nose pliers.
Slow idle speed adjustment
Turn carburetor pilot screw (B) in until it just seats and then back out
1-1/2 turns. Start and warm up engine without load. Move throttle lever
on dash to slow position. Adjust slow idle speed to specified rpm by
moving throttle stop screw (A). Adjust pilot screw (B) until engine
idles at maximum speed and then turn pilot screw out additional 1/4
turn. Re-adjust slow idle speed, to specified rpm.
Fast idle speed adjustment
Air cleaner must be installed to engine before starting. Start and warm
up engine without load. Loosen two control plate bolts (I). Align hole
(B) of speed control lever (C) with hole (D) of control plate (E) and
insert 6 mm (0.24 in.) dia. pin or 6 mm bolt through two holes.
Make sure choke valve is fully opened. Adjust fast idle speed for specified rpm by moving control plate (E). Tighten two bolts (I) securely in a manner to avoid changing specified speed. Stop engine, remove 6 mm pin, and set throttle lever on dash in choke position. Make sure carburetor choke valve is closed completely.
