Carburettors and carburettor components for classic British cars, covering complete SU and Zenith-Stromberg carburettors, service and rebuild kits, needles, jets, floats, dashpot oil, inlet manifolds and the associated tuning components. The SU and Zenith-Stromberg carburettors fitted to British classics are well-understood, well-supported and amenable to home servicing with the right tools and parts inventory.
SU Carburettors
SU constant-velocity carburettors are the dominant carburation type on British classics, in single, twin and triple installations across throat sizes from 1¼ inches (HS2) through 1½ inches (HS4, HIF4) to 1¾ inches (HS6, HIF6) and 2 inches (HS8). Complete carburettors, fully reconditioned exchange carburettors, and individual SU components are stocked across the major applications. Identifying SU type is the first step when ordering parts, the carburettor body type, throat size and tag number determine which service parts apply.
Zenith-Stromberg Carburettors
Zenith-Stromberg CD carburettors were fitted to many emissions-era British classics from 1972 onwards, particularly US-market cars where exhaust emissions regulation drove the change from SU to the more easily-tuned-for-emissions Stromberg unit. CD150, CD175 and CDSE variants are supported with service kits, complete carburettors, and the associated linkage and inlet manifold components.
Service Kits, Needles and Jets
Carburettor service kits combining the seals, gaskets, needle valve, floats and other consumables required for a routine service are stocked across the major applications. Needles and jets are application-specific, the correct needle profile is critical to correct mixture across the engine's operating range, and even within an SU type, several needle profiles may apply depending on engine specification and market.
Inlet Manifolds and Linkage
Inlet manifolds for twin and triple SU installations, gaskets, manifold heat shields and the associated linkage hardware are stocked across the major applications. Performance inlet manifolds, including triple-SU installations on engines that originally had twin SUs, and the Weber DCOE conversions popular for performance applications, are supported for the most common conversions. The MGOC Spares British Classic Car Parts Carburettor & Components range encompasses complete SU and Zenith-Stromberg carburettors, service and rebuild kits, needles, jets, floats, inlet manifolds and tuning components for the British classics we serve. MGOC Spares is constantly expanding our range for these non-MG British classic marques, and new lines are being added to this section regularly.
