SCREW SET A

The key to any successful carburettor overhaul is to renew as many of the jets and these Screw Sets and their springs as possible - the old springs will have weakened, the old adjustment set screw worn with possibly damaged threads, making it difficult to keep the carburettor in tune.

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