Scooter Enricher Working.AVI
Scooter Enricher(Choke) and how it works. The Default of the Enricher(Choke) on a Scoot is the Plunger is Retracted when Cold. Once you start the Engine it receives Voltage and starts to Heat up the Element inside and the Plunger starts to Extend out to shut off the Extra fuel from coming in. It takes about 2-3 minutes for it to fully extend and it extends about 1/4 inch. Once fully Extended it completely blocks the fuel opening and no more extra fuel is feed to the engine. Once you shut the engine off the Plunger will Retract as it cools and it will be ready for the next cold start to allow extra fuel to the engine.
