2. All models with a 1.6 engine and models with a 1.3 engine produced before August 1982 are equipped with an automatic choke with electrical heating.
3. Starting with engine number 0832150 (manual transmission) or 0858780 (automatic transmission), on models with a 1.3 engine, a manual choke is installed.
4. Carburetors are very similar to each other except for the choke device (cold start devices).
5. On the latest versions of the 1.3 engine models with automatic choke, a special valve is installed to eliminate the tendency of the engine to misfire under heavy acceleration between 2700 and 3500 rpm. This valve (part No. 96009298) can be installed on earlier carburetors with automatic choke.
6. The carburetor includes enrichment and compensation systems that allow for optimal carburetor operation in any engine operating mode. The accelerator pump is mechanical.
7. New carburetors with manual choke on 1.3 engines have a mixture leaning device (lowering the air damper). They have an air damper that opens immediately after the engine starts, depending on the degree of vacuum in the intake manifold, so that the mixture does not become over-rich during engine warm-up.
