INSPECTION
Gasoline is extremely flammable and is ex
plosive under certain conditions. Perform this
operation in a well ventilated area and do not
smoke or allow sparks in the area.
1. With the engine stopped, disconnect the fuel line
from the carburetor and check if fuel is flowing
out of the fuel line.
The fuel valve is normal if fuel ceases to flow out
of the fuel line after the remaining fuel (5-10
cc) has been drained out of the fuel valve and
fuel line thoroughly. Should fuel fail to stop
flowing out of the fuel line, check the vacuum
tube for blockage.
2. Disconnect the vacuum tube from the intake
pipe and apply vacuum to the vacuum tube. The
fuel valve is normal if fuel flows out of the fuel
line when vacuum is applied. If fuel does not
flow out of the fuel line when negative pressure
is applied, do the following;
•
Clean the vacuum tube with compressed air.
