Main Jet Holder, Amal, 900 Series 600 for Triumph

Brand new Amal main jet holder, this is a true Amal part and works with all concentric carbs. While you have the carb apart you may want to use a gasket kit or a rebuild kit depending on the condition of your carbs. You will also want to check the play in your carb slide. A worn carb slide will cause erratic idle and the bike to shut down at idle while sitting.
