CARBURETOR CLEANING
● After removing all parts, blow open air and fuel
passages in the carburetor body with compressed air.
CAUTION
•Cleaning the air and fuel passages with a piece of
wire will damage the carburetor body or fuel pump.
● Assemble in the reverse order of disassembly.
CAUTION
•Tightening air screw against its seat will damage the
seat.
NOTE
•Be sure to install the needle jet with the smaller hole
toward the float chamber.
•Install the air screw and its O-ring and washer in the
order as shown in the drawing. If the air screw and
carburetor body are replaced with the new ones,
adjustment is necessary.
CARBURETOR INSPECTION
● Connect an ohmmeter to the auto bystarter wire
connector terminals and measure the resistance. If the
resistance is greatly out of specification, it indicates a
faulty PTC in the auto bystarter. Replace the auto
bystarter.
NOTE
•The auto by starter might be normal if the resistance
is only slightly out of specification. However, be sure
to check all related parts for trouble.
•Refer to the Model Specific manual for specified
resistance.
● Remove the carburetor and let it cool down for 30
minutes. Insert a vinyl tube into the fuel enrichening
circuit and blow into the tube.
● Air should flow into the circuit.
● If air does not flow into the circuit, replace the auto
bystarter.
