Gasoline goes bad with time and begins in as little as 3-4 weeks. This effect is known as varnishing. Jets and passageways within carbs become obstructed when varnishing occurs.

Most carburetor problems seem to come after the motorcycle was stored or not started for a while. If it won't start or only runs with the choke lever pulled out, you have one or more jets obstructed by gummed or varnished fuel. Notice the enrichening lever...most of the motorcycle carbs have enrichening passages inside the carburetor that WHEN THE THROTTLE IS CLOSED, provide the rich air/fuel mixture to start the engine. If you open the throttle any at all it cuts this enrichening out of the system. So if you are having trouble starting and everything looks ok, see if closing the throttle helps. This does not apply to carbs with a butterfly choke.
