6. Carburetor

b. Judgments of the main check valve

● As illustrated, hold a plastic pipe on the check

valve and blow and suck air by your mouth. If the

air is stopped by blowing, and open by sucking, the

valve has no failure.

● In case of failure, soak the valve into gasoline for

about 10 minutes and repeat blowing and sucking

several times.

If this is not successful, replace the body assembly.

● Make sure to check the valve in case fuel is not

supplied though the priming pump is operated.

c. Throttle valve normality check

● Check that no wear exists in the throttle valve slide.

Carefully slide a screw driver tip along the plunger's

contact surface.

If the screw driver tip catches in a groove, replace

the carburetor assembly with a new one.

● Check that no wear exists on the jet needle.

If there are signs of vertical linear flaws or wear,

replace the carburetor assembly with a new one.

Even small damage will increase fuel

consumption.
