Service Points of Disassembly
The following parts must not be disassembled at the time of
disassembly.
(1) Choke valve and choke shaft
(2) Inner venturi
(3) Throttle valve and throttle shaft
A Return spring/choke rod removal
(1) When the spring is removed, avoid prying it with undue
force or any other attempt that can cause damage to it.
(2) Press the end of the choke rod to force the rod out. Avoid
applying a strong force to the plastic grommet of the rod
fit-in hole.
B Float chamber cover removal
(1) Since the screws require great force to loosen, use a
Phillips screwdriver that exactly fits in the cross recess in
the screw heads.
(2) To remove the float chamber cover, slowly lift it, while
using care not to give damage to the float. Don’t tilt the
main body, as the pump discharge weight and the related
parts may come out and could be lost.
C Pump weight/ball
Turn the main body upside down to remove the weight and
ball.
D Main jet removal
To remove the main jet, be sure to use a screwdriver whose
tip exactly fits in the slot of the jet.
