Aftermarket copies of the Zenith 361V or 36IV carburettors, factory-fitted to late Series 2a and early Series 3 Land Rovers with the 2.25 litre 4 cylinder petrol engine (and compatible with all Series 2, 2a or 3 petrols with an adaptor and accelerator linkage assembly to suit), are notoriously unreliable. Sometimes they work OK at first, then start coughing and spluttering when a nitrile O ring succumbs to modern fuel additives; sometimes they're driveable but disappointing, thanks to a combination of casting defects, poor quality parts and assembly errors. Quality varies across suppliers and manufacturers, but none work nicely and reliably out of the box.
The Weber 34ICH carburettor works more reliably out of the box and is marketed as a Series carburettor. It's a workable solution, but not ideal. Unlike the Zenith, which was specified by Land Rover, the Weber is a generic carburettor that happens to work acceptably on a Series. A good Zenith in good tune is better. The difference is not night and day, but it's real and noticeable.
We source the aftermarket Zenith copies with the highest quality alloy castings. We disassemble them and turn them into carburettors that are as good as our restored Genuine Zeniths. We then road test each carburettor before shipping it. We back it with a one-year Series Magic warranty.
The best Zenith copies have excellent castings, but their assembly surfaces need to be lapped flat (as the CNC head passes over them at the factory, it releases stresses in the castings, which cause them to distort slightly). We replace the float bowl O-ring with one that's far more resistant to the additives in modern fuels—a common cause of Zenith deterioration in use. We bench test various components and replace any faulty or substandard ones, and rectify any assembly errors. Once it's all back together we road test it on a Series. It must pass the road test with flying colours to get our stamp of approval.
