High idle speed — check and adjustment

Disconnect vacuum hose from choke diaphragm assembly (rice. MCC06.013).

Set lever (A)...



...to the highest stage of the high idle cam (IN).



Start the engine and check the high idle speed value (2600±200 rpm

If the speed does not match the required, adjust it with a screw (D) (see fig. MCC06.011). Turning the screw clockwise increases the speed.

Connect a vacuum hose to the choke mechanism and verify that the high idle is canceled.
