US Patent:

6540212, Apr 1, 2003

Filed:

Feb 1, 2002

Appl. No.:

10/060446

Inventors:

Michael P. Burns - Millington MI
Gary U. Gliniecki - Ruth MI
George M. Pattullo - Caro MI
James E. VanAllen - Clifford MI

Assignee:

Walbro Corporation - Cass City MI

International Classification:

F02M 308

US Classification:

261 71, 137382, 251227, 261DIG 38, 261DIG 84

Abstract:

A fuel needle valve assembly of a carburetor has a retainer which yieldingly restrains the rotational fuel flow setting capability of the needle valve. The retainer engages a shank of the needle valve and a parallel shaft, both of which project from the carburetor body. The retainer exerts a force which laterally displaces the projecting shank with respect to the shaft. The retainer has sufficient strength to ensure the factory set rotational setting of the fuel needle valve does not alter when a limiter cap is press fitted to a distal head of the needle. Furthermore, wherein the shaft is also a shank of a second needle valve, the same retainer laterally displaces the projecting shanks of both needle valves.
