NEEDLE JET MK1 CONCENTRIC .106
Needle jet, .106 size, for the Amal Mk1 Concentric carburetor.
This is a needle jet for the Amal Mk1 Concentric carburetor, sized .106. The needle jet is one of the fixed metering pieces inside the carb body that works with the jet needle to control fuel delivery through the mid-throttle range. Amal stamps a size on these so you can match what your carb originally ran or step up or down when tuning.

If you're rebuilding or re-jetting a Mk1 Concentric, this is a part worth checking against wear, since the needle jet bore opens up over time and throws off your fueling even if everything else in the carb is fresh. Confirm the .106 size matches what your carb calls for before ordering, since Mk1 Concentrics were built with a range of needle jet sizes depending on application.
