The interior of the car can be heated by the engine warmed air being ducted into the front compartment and controlled by a lever on the heating system tunnel. Engine ignition is by a battery, ignition coil and distribu- tor which is driven by a gear on the camshaft. The engine is started by an electric starter motor which is mounted on the gearbox casing and is controlled by a lever located behind the gearchange lever. that rear air ducting panels are not strained or the mating faces damaged.

Extract the pushrods, making a careful guides have no stop ring during the press fitting, the note of their location.

Cylinder head installation: To refit the cylinder head proceed as follows: Place a new cylinder head joint on the cleaned faces of the cylinder barrels. Insert the rocker pushrod and lubrication pipe sleeves together with the relevant gaskets and rings. Fit the washers and nuts to the studs and tighten to fingertight. It is recommended that to zero the internal micrometer Fiat ring gauge C.672 is used (see FIG 1:23). If bore wear or ovality is between.0059 and.0079 inch the cylinder bore may be honed.

Insert a.0079 ±.00197 inch thick oil paper gasket between the crankcase and cylinder bottom face and a FEELER GAUGE C.316.0236 to.0275 inch thick graphitized asbestos gasket between the cylinder and cylinder head. The compression of the gaskets on assembly will eliminate any very small differences between the two mating surfaces. FEELER GAUGE Place a piece of 'Plastigage type P G - 1 ' along the full w i d t h of the bearing insert along the crankshaft longitudinal axis (see FIG 1: 3 0 ).

The amount of charge passing to the manifold is controlled by a throttle butterfly valve from an accelerator pedal operating a lever secured to the throttle valve shaft via a cable. pulling the device control fully across through lever 38 and rocker 36, the valve 33 is lifted from its seating and brought into the 'fully open' position. Refer to diagram 'A' (FIG 2:5).

Under these conditions the valve 33 closes the air hole 27 and the mixture hole 29 and uncovers mixture orifices 30 and 32 which also communicate with the starting jet 46 through a duct 26 and air holes 35. 3 Engine warm-up: As the engine begins to warm up to its normal operating temperature, gradually push home the starting device lever so as only to supply the engine with the richened charge enabling the cold engine operation to be smooth and regular. The Weber 26.IM B carburetter has undergone a number normal operating temperature. Any excessive clearance of minor changes during the development of the Fiat 500 caused by wear or the throttle valve butterfly distorted are models, but no changes in servicing procedure are made liable to cause irregular engine operation which will be necessary. FIG 2:12 illustrates the starting device fitted to 26.IMB.4 and later carburetters. It differs from earlier units in detail, principally in having fewer starting mixture orifices 30 and 32 into the mixture duct 26. 2:8 Carburetter operation adjustment, Weber 26.
