46-04-02 CULVER: (Was Service Note 6 of AD-730-2.) Applies Only to Model LCA Having Stromberg Model NA-S3A1 Carburetors Installed.

When inspecting or replacing carburetor float needle or needle seat, a check should be made to assure that when a rubber tipped needle is used, a seat having rounded edges is installed. Sharp-edged seats, when used with a rubber tipped needle, will cause sticking and cutting of the rubber tip.

(This matter is also covered by Continental Service Bulletin No. M45-6 dated May 25, 1945, and Stromberg Aircraft Carburetor Service Bulletin No. 71.)
