What is a Carburettor Main Jet Cutoff?
A carburettor main jet cutoff is designed to eliminate backfiring on hard deceleration. When you decelerate hard, it creates a high vacuum which activates the valve. This activation reduces the airflow, which, in turn, richens the mixture. This slightly richer mixture eliminates backfiring.
A broken main jet cutoff won't stop backfiring, so it's imperative you get it replaced quickly.
