Have you removed the carburetor float bowl and checked it for water and debris? After sitting for three years the float and needle valve may be stuck, not letting in enough fuel to let engine run under load.

I see it has no float bowl! But it has the upper body, which houses the float and needle valve. Here is diagram of carburetor. See link below.

I would recommend a full disassembly and cleaning of the carburetor!
