Carburetor Volvo 1800 SUHS6 (2-Bolt) (B18B/D)

This category gathers wear and rebuild parts for the SU HS6 with 2-bolt flange connection, fitted to the dual-carburetor B18B motors in the 1800 series.

The group includes metering needles for the correct mixture, springs for the piston and float, plus screw, spring washer and retainer for the flange. There are also gaskets, washers and bushings – the bushings are typical inspection points since play in the throttle shaft creates false air and an unsteady idle. During an overhaul you usually replace needles, gaskets and worn bushings all at once so both carburettors can be synced cleanly.
Bear in mind that the flange pattern (2-bolt) and needle profile determine the fit, so check the version against your motor before ordering.
