ABSTRACT:
A carburetor for use with an internal combustion engine has a fuel and air mixing passage, a choke valve with a valve head disposed at least partially in the fuel and air mixing passage and an air bleed passage with at least a portion that is communicated with the choke valve head when the choke valve is in its closed position to at least partially restrict air flow out of the air bleed passage when the choke valve is closed. The air bleed passage preferably provides air to a fuel circuit of the carburetor when the choke valve is open. When the choke valve is closed the air flow through the air bleed passage to the fuel circuit is at least partially restricted to provide a richer fuel and air mixture to the engine during a choke assisted start and warming up of the engine.
