Rough idle, poor cold start or fuel smell around the carburetor is often caused by a worn needle valve or hardened gaskets – classic wear points on SU carburettors of the HS6 type. This category gathers service and wear parts for the B20A from the 1970 140, where the B20 replaced the earlier B18.

The group includes needle valves that control the fuel level in the float chamber, gaskets for sealing against the intake and flanges, plus springs, screw, nut, washer, spring washer and retainer that belong to the assembly. During an overhaul, the needle valve and gasket set are exactly the check points when the idle wanders or the engine floods.
The selection covers parts for removal, cleaning and refitting of the carburetor – from small fasteners to seals that are often replaced together during a rebuild.
