Manufacturer's Description

The 600 Series AMAL Carburetter for four stroke applications has been re-designed to improve performance and wear. The new carburetter incorporates changes in materials which reduce the rate of slide and body wear and a precision engineered idle circuit which improves the pick up performance from idle and reduces fuel consumption. The precision manufactured forged alloy, hard anodised throttle slide has a low friction surface for smoother operation and greater wear resistance. The material of the carburetter body has a “passivated” finish which resists corrosion, whilst the ethanol resistant, puncture proof StayUp float and viton tipped alloy needle valve improve control of the fuel flow.
 
A new easily removable pilot jet provides precise metering of the idle circuit. The jet, which is located in the opposite position to the pilot air screw, is manufactured to tight tolerances allowing it to be replaced with minimum disruption to the adjustment of the carburetter. Initially the size of the jet replicates the 622/107 pilot bush. Other sizes will be available shortly. Removal of the jet allows access to the rest of the idle circuit for servicing. The new jet cannot be fitted to earlier versions of the Mk1 Concentric.
