SPRING AIR SCREW

The Air Screw Spring is one of many critical wear items in the carburettor. Renewing this will help keep the carburettor/s from 'self adjusting', and along with the new jets, including main jet, needle jet and slow running jet will help restore the carburettor back to full performance and economy - check the schematic to see exactly which parts you should order.

• Order new carburettor seals and gaskets at the same time.
• Consider new throttle cables as well!
