Abstract
A carburetor improvement comprises a flow passage through which fuel vapors created in a fuel bowl are drawn off to a chamber having a first outlet through which fuel vapors are directed to a canister and a second outlet through which fuel vapors are directed to an air passage in the carburetor. A solenoid includes a valve member movable between a first position opening the first outlet and closing the second outlet and a second position closing the first outlet and opening the chamber outlet. The valve member is moved to its first position when the engine is off so fuel vapors are collected in the canister and to its second position when the engine is operating so fuel vapors are directed to the air passage.
