CARBURETOR Fiat Uno

Fiat Uno cars are equipped with various types of carburetors, which can generally be divided into two groups. Weber Carburettors 32 ICEV or Solex C32 DISA single pass and have been used in engines 900 and 1100. Weber Carburettors 30/32 DMTR or Solex C 30/32 CICs are of the register type” and fitted with engines 1300. The difference between Weber and Solex carburettors in this group is the use of nozzles of different sizes.

In the engine 900 The ES used a different version of the carburettors, adapted to the production of leaner fuel-air mixtures and equipped with a device that cuts off the outflow of emulsions during engine braking. The device is activated at rotational speeds exceeding 1350 rpm. The device control system is placed in the immediate vicinity of the electronic ignition module.

On the "register."” in the partial load area of ​​the engine, only the first pass throttle is operative, on the other hand, at full load, both passages operate and the suction air flow increases.

By checking the carburetor setting, regulatory data should always be used (it happens often, that new cars have improperly set carburetors and ignition systems). Much of the regulatory work requires specialized instrumentation, though there are also such, for which simple aids are enough. However, you need a sense of hand and experience for each activity (e.g.. measuring the throttle opening with a drill). The following descriptions of the adjustments do not cover these "grips"” monterski. However, every experienced mechanic should have no problems at work using the tips and technical data provided.
