Engine
Refitting
- Fit the oil pump on the drive shaft.
- Fit the pipe gasket, inserting it into the crankcase.
- Insert the screws of the pump into the crank-
house and tighten them.

Fuel supply

The vehicle has a membrane pump controlled by
the vacuum generated in the intake manifold.
Therefore, the tank has an outlet at the lowest
point which sends fuel to the pump and then to the
carburetor.
To make sure this is working properly, proceed as
follows to determine the quantity supplied:
- Start the engine, bring it to normal operating tem-
perature, then switch it off.
- Disconnect the fuel supply pipe on the carburettor
and put it into a graduated burette.
