Adjustingthe carburetor
NOTE: The grinding parts are equipped with an electronic
ignition to limit the speed. The carburetor also has a fixed
jet which cannot be adjusted.
At the factory the idling speed has been set to approx.
2,500 1/min., but the running-in process of a new engine
may require slight readjustment of the idling speed.
Set the idling speed with a screwdriver (width of blade: 4 mm/
0.16").
The screwdriver shown (order number 944 340 001) has a
molded-on lug to assist in adjustment.
