You pay for what you get. It’s an old adage which means good quality, longer lasting items cost a little more than cheaper, short life alternatives. Made in England by the company that made them originally – how much better can you get than that? Well, AMAL Carburetters has taken its Mk1 Concentric and given it a long lasting makeover. The 900 Series AMAL carburetter for four-strokes has been redesigned 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 too. The precision manufactured forged alloy, hard anodised throttle slide has a low friction surface for smoother operation and greater wear resistance. The carburetter body has a corrosion resistant passivated finish and the all important ethanol resistant, puncture proof StayUp float and viton tipped alloy needle valve improve control of the fuel flow.
A new, easily removable pilot jet gives precise metering of the idle circuit. The jet, opposite the pilot air screw, is manufactured to tight tolerances allowing replacement with minimum disruption to adjustment. All sizes are available. Removal of the jet allows access to the rest of the idle circuit for servicing. The new jet cannot be retro fitted. The carb is available in 28mm, 30mm and 32mm and with right/left-hand pilot adjustment. More from Amal's website: www.amalcarb.co.uk
