Carburetor Volvo 240 SU (B20)

Rough idle, leaking metering needles and worn shaft bushings are classic reasons to go through an SU carburetor on the B20. This category gathers wear and rebuild parts for SU setups, both single HIF6 and twin installations, where the right needle and spring decide how the mixture follows load and engine speed.

Volvo expertise since 1999

We're here for you and your Volvo

The group includes metering needles, springs, screws and nuts, washers, plugs, spacer sleeves and bushings – parts that are typically replaced when you true up a worn carburetor or rebuild the whole package. A common checkpoint is precisely the bushings and shaft play: slop in the throttle shaft causes false air, high idle and a mixture that is hard to set, and then a new needle won't help until the shaft area is tight again.

The parts are grouped by function so you can pick out what you need for a single overhaul or a complete rebuild of twin SU.
