Plugs for carburetors

摘要

In accordance with one implementation, a carburetor includes a body having a fluid passage formed therein and a counterbore located along the fluid passage. The counterbore has a first sealing surface and a central axis, and the body further includes a second sealing surface located radially closer to the central axis than is the first sealing surface. The carburetor also includes a plug affixed to the body at the counterbore and in contact with both of the first and second sealing surfaces. Engagement of the plug with the two sealing surfaces may improve the connection between the plug and carburetor body. In at least some implementations, the plug may be held in place without aid of an adhesive or other secondary connector or connection aid.
