While Mike is right about how a real choke works, not every old bike has a plate choke.
Most of the Nighthawk carbs I've seen have "chokes" that are actually fuel valves. Instead of a plate to restrict airflow, the cable opens a simple valve that allows fuel to flow more freely than through the jets. This increases the fuel:air ratio to allow the cold start. Aircooled engines are, by their nature, cold blooded so to speak. Most small aircooled engines need extra fuel to start, and that means using the device (choke or enrichment) when you start it.

Or do all older carb motorcycles require the choke? On Tuesday, 24 May 2016 15:03:26 UTC-4, blackbird wrote: > > Hi Group, > > New rider here.
