Carburetor Inspection
WARNING
Gasoline is extremely flammable and can be explo-
sive under certain. Turn the engine switch OFF. Do
not smoke. Make sure the area is well ventilated
and free from any source of flame or sparks; this
includes any appliance with a pilot light.
•
Inspect the carburetor body for damage. Flange sealing
surfaces should be smooth and free of burns and nicks.
•
Turn the throttle and choke shafts to check that the throttle
and choke butterfly valves move smoothly.
If the valves do not move smoothly, replace the carburetor
body and/or throttle shaft and choke shaft assembly with
new ones.
•
Check the gasket on the carburetor body.
If the gasket is not in good condition, replace it with a new
one.
•
Check the other parts of the carburetor for any wear or
damage. Replace the part with a new one if necessary.
•
Clean and check the float level as follows.
CAUTION
Do not push down on the float during float level
checking.
•
With the float [A] assembly installed onto the carburetor
body, hold the carburetor upside down at eye level. Gen-
tly support the float with a finger and bring it down slowly
so that the float arm tab [B] just touches the float valve
[C]. The float lower surface [D] should be parallel with the
carburetor body mating surfaces [E].
If the float position is not correct, replace the float with a
new one.
