Idle Speed, Check and Adjust

 

 

The engine speed is read at the V-belt with the engine at operating temperature using a photo-electric cell type tachometer.

 

A 1 to 2 cm/0.4 to 0.8" wide piece of aluminium foil should be attached to the front collar of the crankshaft pulley.

Start engine and check speed with tachometer.

 

The engine speed must be between 780 and 840 min-1

(on 16 DA, 17 D between 820 and 880 min-1)
