ADJUSTMENT OF CARBURETOR AFTER REPLACEMENT

Pull throttle lever fully after a while engine running at idle position. When there is Fig. 38 a problem with the engine quick acceleration, adjust H needle (Fig. 38) as follows:

(1)Warm up the engine by pulling the throttle lever fully for one minute.

(2)Keep engine idling and do fine adjustment of the idling speed by turning

H needle (Fig. 38) with a thin slotted screwdriver.

 

 

(3) Pull the throttle lever quickly. If Engine stall happens/ Engine does not reach

 

 

the maximum rpm, do step (4). If there are no problems with the engine quick

 

 

acceleration, go ahead to step (5).

 

 

(4) Unscrew H needle 1/8 turn (45°) with a thin slotted screwdriver.

Adjust H needle through the hole

After pulling the throttle lever fully with no load, retry the step (3).

(5) Push two Limiter caps (Fig. 37) into Carburetor with a flat top of rod.
