Abstract
A fuel removal system for a carburetor with a float bowl carried by a body having a channel extending from the float bowl to the exterior of the carburetor body. An outlet tube is positioned within the channel and is movable from a first position wherein liquid fuel can be removed from the fuel bowl to the exterior of the body, and a second position wherein the outlet tube does not communicate with the float bowl.
Claims21
A fuel removal system for a carburetor comprising:
- a float bowl carburetor body, having a fuel bowl carried by the body;
- a channel formed through the body and extending from the fuel bowl to an exterior of the body;
- an outlet tube received in the channel and communicating axially with the channel;
- and
- wherein the outlet tube is axially movable in the channel from a first position wherein liquid fuel may be removed from the fuel bowl to the exterior through the outlet tube to a second position wherein the outlet tube blocks a portion of the channel to prevent communication through the channel between the fuel bowl and the exterior.
