rod onto the main body.
As shown below, the fuel spray should be
shaped conically. If not, pull out the ac-
celerator pump nozzle and clean the
nozzle with compressed air.

spray is directed between the main body
of the accelerator pump and the throttle
valve, the injection angle of fuel is cor-
rect. If it hits the main body or the throttle
valve, adjust the direction by bending the
accelerator pump nozzle.
