We are having some communication problems I think. By my reading of the diagram on Page 5, Item 147 is a fixed jet, where Item 173 is an adjustable needle. Here is the page from the technical manual that hopefully describes the carburetor:

Your engine is a 91200 (the final 2 in 91202 just tells us it has a rewind starter.) Now, you haven't posted the Code for your engine (the set of numbers stamped on the cowl, right after the Model and Trim which you posted). The Code tells us its date of manufacture. However, the diagram above says that is the description of the carburetor for a 91200. The non-emissions version has an adjustable idle mixture screw, and is applicable only to "Current Version", in diagram A. That whole series of carburetors does not have an adjustable main mixture screw, though an earlier series, fitted to vertical crankshaft engines, did. A pilot jet is an idle jet, and the assembly diagram is telling us that your engine will either have Item 147, a fixed pilot jet, if it is an emissions carburetor, or Item 173, an adjustable idle jet, if it is non-emissions. Yours has an adjustable idle mixture screw, so it is the type marked [2], in the first diagram in the tech manual.

Item 692 is a detent spring, used for clicking into a recess to hold a control in a specific position. I don't know where it fits on the carburetor but I doubt it is relevant at this point.
