Weber 32 Carburetor Overhaul Kit – Fiat 127 – A112

Overhaul Kit for Weber 32 IBA Carburetor – Fiat 127, Seat Fura, and A112

Restore correct fuel delivery and reliability to your vehicle with this Weber 32 IBA carburetor overhaul kit. This set of spare parts is specifically designed for the 20/250, 21/350, and 23/350 series, the single-choke variants that equipped much of the Fiat Group's 903cc engine production. This is the ideal kit for the Fiat 127, the Seat 127 Fura, and versions of the Autobianchi A112 fitted with the 903cc engine.

The heart of this kit is the needle valve (size 1.50 - code 371M), a crucial component for regulating the fuel flow into the bowl. An efficient valve prevents flooding phenomena and ensures that the air-fuel ratio remains stable, guaranteeing a smooth idle and consistent progression. Along with the valve, the kit includes all the special paper gaskets, formulated to withstand the chemical aggression of modern fuels, and the accelerator pump diaphragm.

Replacing the diaphragm and gaskets is fundamental, as these elements tend to harden or crystallize over time. By installing new components, you can regain that prompt throttle response essential for daily driving and rallies. In fact, this maintenance intervention allows for the elimination of seepage and power flat spots, preserving the original mechanical integrity of the engine without having to replace the entire fuel delivery unit.
