Carburetor Volvo 240 SU (1979-84)

Sluggish throttle response, a leaking idle or a lever that won't return are often caused by worn small parts in the SU carburetor rather than by the carburetor body itself. On the B21 engine in the Volvo 240 between 1979 and 1984, it is precisely the springs, joints and adjusting screws that age first and upset the synchronisation.

This category gathers wear and adjustment parts for the SU carburetor. The group includes adjusting screws for idle and mixture, return springs and springs that hold the throttle plate in place, levers for the linkage, plus nuts, washers and spacer sleeves for the mounting. During an overhaul, the return spring's tension and the adjusting screws' threads are typical checkpoints – a fatigued return spring gives a hanging idle, and worn threads make the idle impossible to set stably.

The parts are sorted by model year because the design of the 240 changed during this period, so always check against your car before ordering.
