JET,#120

The main jet is one of the most critical wear items in the carburettor. Renewing this along with the jets, including throttle valve, 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 genuine throttle cables as well. You will be glad you did once they are fitted.
