Governor system adjustment method
The governor unit is a centrifugal flyweight type and is installed on the governor gear.
Since it automatically adjusts the throttle valve of the carburetor by means of a link mechanism, it is possible to
maintain a constant engine speed, even with load variations.
(1) Turn the speed control lever to the full speed position, making sure that the carburetor throttle valve is fully
open.
(2) Hold the top of the governor shaft with the plier and turning it clockwise as far as it will go. Tighten the bolt on
the governor lever.
