EXCERPT:

Adjustment of the microswitch
Regular operation: during engine operation at idle speed, the engine should be retarded, with the microswitch operating the R2 points; as soon as the accelerator lever is moved from the position with the tappet at the 20 mark of the idle speed (maximal height), the microswitch must open the circuit and allow points Rl to function.
Check: with engine off, but hot , with idle speed cam rotated so that its tappet is aligned to the 20 mark (with carburetors butterfly valves slightly open), move the microswitch tab towards the body of the microswitch itself.
You should not hear any click sound, which indicates the opening and the closing of the microswitch.
Such a click will be heard instead, when the accelerator lever liill be moved slightly from the above-mentioned position, as when accelerating.
To adjust, it will be necessary to to eventually work on the nuts mounted on the carburetors lever in reference to the arm on which rate the microswitch lever.
If, when cold, the engine idle speed exceeds 1600 rpm's, check the microswitch adjustment: the engine timing could be advanced.
If the engine, while being progressively accelerated during driving, runs unevenly, the microswitch is keeping the engine retarded too long, therefore it is necessary to adjust the lever travel as mentioned above.
The microswitch needs no maintenance , with only a periodic check every 15,000 kms. of its cables and contacts to ensure that no current interruptions exist and that the cables are well insulated.
If a cable must be disconnected, or if one of the cut-out switch ground cables is missing or disconnected, the engine will idle at 1400 rpm's rather than at 1000 rpm's. To check whether the microswitch is functioning properly,directly ground the cable coming from the distributor. A decrease in engine speed will be noted since the distributor retard points will be activated.
