FUEL SYSTEM
● Connect the battery to the auto bystarter terminals and
wait for 5 minutes.
● Insert a vinyl tube into the fuel increasing circuit and
blow into the tube.
● Air should not flow into the circuit. If air flows into the
circuit, replace the auto bystarter.
● Check the resister if the auto bystarter is normal but
engine is still hard to start.
● If there is a broken wire in the resister, current will not
flow to the PTC and the auto bystarter will not operate.
● If there is a shorted wire in the resister, current of a
higher voltage than specified will reach the PTC. This
will cause the fuel enrichening circuit to close too soon,
and starting will be difficult.
THROTTLE VALVE
REMOVE
● Throttle valve.
● Throttle cable.
● Throttle valve spring.
● Needle clip.
● Seal cap.
● Clip.
● Jet needle.
ASSEMBLY
● Install the jet needle into the throttle valve and be sure
to fixes the needle clip.
● Route the throttle cable through the spring and
compress the spring fully.
● Attach the throttle cable end to the bottom of the
throttle valve and thread the throttle cable through the
slot in the valve.
● Align the cutout in the throttle valve with the throttle
stop screw on the carburetor body and install the valve
on the carburetor.
•Be sure to check if the cutaway turns toward air
cleaner. If it is assembled reversely, the engine may
spring up like fountain due to the throttle valve not
going down.
● Operate the valve after installing the throttle valve.
