Carburetor Volvo 140 Stromberg (B20B)

The group includes gaskets and O-rings that often dry out and start to leak, return springs and springs that control the throttle shutter's return, plus screws, nuts, washers and lock washers for mounting and assembly. During an overhaul, the gasket set, worn springs and deformed washers are typical inspection points – also check that the return spring pulls the shutter back fully. Always compare against your existing setup, since the B20B was supplied with twin carburettors and the parts occur in pairs.
