2928/030 Throttle needle 2C3
Amal Mk II Concentric carburetor throttle needle, profile 2C3, catalog number 99-7074 (Amal 2928/030, now 2928030).
This is the throttle needle out of an Amal Mk II Concentric carburetor, catalog number 99-7074, also carried under the Amal factory number 2928/030 with a needle profile marked 2C3. It's the tapered needle that rides in the needle jet and moves with the throttle slide, shaping how much fuel gets pulled into the airstream as you open the throttle past idle.

Our catalog shows this one turning up in the Amal Mk II Concentric carb figures used on the T140E and T140D, and it's since been picked up under the newer factory number 2928030. If you're matching parts against an older book that still lists 2928/030 or 99-7074, know that it's the same needle just renumbered.
Needle profile matters for how the carb runs through the mid-range, so if you're rebuilding or troubleshooting a flat spot on throttle, this is one of the parts worth checking against what your carb originally had fitted. Call the shop if you want help confirming the 2C3 profile is right for your setup.
