9. Checking and adjusting the carburetor ass'y
(1) Checking the Carburetor Ass'y
[48]<48>
After disassembling the Carburetor Ass'y
[48]<48>
, check its parts for wear, deformation, and clogged
holes. Use compressed air to remove or blow off any foreign particles or dust found. If deformation or
wear is found, replace the Carburetor Ass'y
[48]<48>
or its faulty parts.
(2) Adjusting the Carburetor Ass'y
[48]<48>
Adjust the throttle valve opening for idling by turning the idle adjust screw. To increase the engine
speed, turn it clockwise. To reduce the engine speed, turn it counterclockwise. If the Saw Chain
[225]<225>
rotates during idling, reduce the engine speed so that the Saw Chain
[225]<225>
does not
rotate during idling. On the other hand, if the engine speed for idling is too slow, the engine might stop
during idling. In such case, increase the engine speed within the range that inhibits the Saw Chain
[225]<225>
movement.
