Frequently asked questions

What is the idle adjusting needle used for?
The idle adjusting needle sets the idle mixture on the Zenith Stromberg CD175 constant-depression carburettor fitted to the Rover 3.5 V8. It seats within the jet to meter fuel at idle as the carburettor's air valve rises and falls, controlling how rich or lean the engine runs at tickover.
Which vehicles used this carburettor needle?
This needle suits the Rover 3.5 V8 running the Stromberg CD175 carburettor, typically the Range Rover Classic, Series 3 / Stage 1 V8, and carburettor V8 Defender models from the 1970s to mid-1980s. Because it's specific to the CD175 setup, confirm your carburettor type rather than relying on model year alone.
Why would the idle needle need replacing?
An idle adjusting needle wears at the metering taper over time, which upsets the idle mixture and makes tickover hard to set on the Stromberg CD175. A bent or worn needle can cause an uneven or hunting idle. Replacing it restores accurate mixture adjustment on the Rover V8.
