OVERHEATING: On a hot day, your Triumph BSA, Norton or other make of motorcycle can suffer from an overheated carburettor after running at high speed or operating at low RMP for long periods.  This can cause the petrol to ‘boil’ in the float chamber creating poor running at slow speeds.

 

BSA even went to the trouble of producing a Service Bulletin (#17/71) advising dealers how to assist owners overcome these problems.  See picture.

 

These insulating washer kits are now available for AMAL equipped motorcycles, with a 2 inch carb stud spacing, to help reduce the problem of carburettor overheating.  The kit comprises a 3mm thick washer made from asbestos free Novus 30 as the main insulator - see spec. sheet.  The kit includes an O-ring - NBR (Nitrile) 70 ShA - see spec. sheet.  Also included are 2 nylon washers to improve insulation between the mounting studs and the carburettor.
