Cleaning the short oil unit
Short oil unit 1 is fitted into socket-head screw 2 on the lower side of the engine. Insert an Allen key into the socket and unscrew the oil drain screw.
Remove the oil unit, thoroughly clean its components and blow them with low-pressure compressed air. Check the O-rings for damage and if necessary replace them.
Replace the oil unit with the screw and tighten the latter to 10 N·m.

Cleaning the long oil unit
The long oil unit is fitted into hexagonal-head screw 3 next to the engine number. Remove the screw with the oil unit, thoroughly clean the components and blow them with low-pressure compressed air. Check the O-rings for damage and if necessary replace them.

Carburetor - Idle speed adjustment
The adjustment of the idle speed strongly affects engine start- ing, i.e. an engine whose idle speed is properly adjusted is easier to start than an improperly tuned engine.
The idle speed is adjusted by means of adjusting roller 1 and mixture adjusting screw 2. The adjusting roller alters the base position of the throttle valve; the mixture adjusting screw adjusts the idle speed mixture, which comes to the engine through the idle speed system. Turning the screw clockwise decreases the quantity of fuel (lean mixture); turning it anti-clockwise increases the quantity of fuel (rich mixture).
To properly adjust the idle speed, follow these steps:
– Turn in mixture adjusting screw 2 until it stops, then turn it to obtain the basic adjustment prescribed by BETAMOTOR (see engine specifications in Chapter 3).
– Warm up the engine.
– Using adjusting roller 1, adjust the standard idle speed (1400- 1500 rpm).
– Slowly turn mixture adjusting screw 2 clockwise until the idle speed begins to decrease. Memorise this position. Now slowly turn the mixture adjusting screw anti-clockwise until the engine speed starts to decrease again. Choose the point between these two positions where the idle speed is higher. Should the engine speed increase considerably, reduce it to the standard level and repeat the above procedure.
