Zenith Inat carburettors: German engineering, renewed down to the last ring
The Zenith Inat is a well-known two-stage carburettor that was fitted in the sixties, seventies and early eighties to various models from Mercedes-Benz, Opel and BMW. They are robustly built, respond well to setting up and strike a fine balance between comfort and power. After decades of driving, long storage or minimal maintenance, an overhaul is often exactly what they need. And that is precisely the solution we offer.
Which cars came with the Zenith Inat?
These carburettors were common on mid-range and executive cars of German make. Think of:
Mercedes-Benz
- W114 and W115 such as the 250 and 280, produced from 1968 to 1976
- W123 250 models, between 1976 and 1985
Opel
- Commodore A and B, between 1967 and 1977
- Rekord C and D, produced between 1966 and 1977
BMW
- E3 and E9 models such as the 2500, 2800 and 3.0, from 1968 to 1977
Depending on the engine type and specification, these cars were fitted with a single or twin Inat carburettor.
A complete overhaul, without compromises
We overhaul the Zenith Inat completely, with a professional approach. Every overhaul takes an average of 14 hours of craftsmanship, in which we disassemble, clean, inspect and renew everything. The service kit we use consists of 36 new parts per carburettor, including:
- All rubber gaskets, fully resistant to modern fuels
- Fibre sealing rings
- Two new diaphragms for the accelerator pump
- Four new felt seals for the body sealing
- A float needle with a new seat
- Various rings, seals and O-rings
- Various springs
Everything is ultrasonically cleaned, checked for distortion and rebuilt with precision. If you wish, we also set the carburettors up on the engine after fitting.
Why choose our overhaul?
An old Inat that is hard to set up, suffers from leaks or runs unevenly is a frustration for many classic car enthusiasts. With our overhaul you get the maximum out of this dependable carburettor and let it do its work cleanly and crisply again. This is a thorough approach rather than a quick fix: everything is new, except the body itself.
And of course you can also come to us for technical support or additional parts.
