FIAT used Weber as the primary source of carburetors throughout the 60’s and 70’s. Factory changes in carburetor types occured during engine displacement upgrades, changes in regional laws (such as environment legislation), or during model year changes. It is important to know what engine, cylinder head, carburetor, intake manifold, and exhaust system you have on your FIAT. Understanding what you have allows you to make an educated decision about what you need. If you are not 100% sure of what you have then take a few moments to check - many a Spiders with “2000” badges have 1800 engines and vice-versa. Engine Identification The engine identification number is stamped into the engine block near the oil filter. It is sometimes covered in grime, carburetor cleaner or degreaser and a brush will allow you to read it. On the Spider 2000 engine (1979-1985) it is located just to the right of the oil filter. On all Spiders manufactured prior to 1979 it is located above the oil filter. Exhaust System Identification, 1. Ignition system: as necessary, new plugs, wires, distributor cap, rotor, vacuum advance capsule and hose, coil, pickup, points, condensor, points gap, dwell setting. Set the ignition timing to exactly what your car’s instruction book calls for. If you have Marelli electronic ignition (1979-1985) be sure the vacuum advance is working properly. Type of Cold Start Device: Manual, Automatic, Electrical, Intake and Carburetion. A reference on how to reset and tune a single carburetor
