I just finished a rebuild on my engine and the carburetor. I've got the motor working great, but the carb is giving me issues. First, I'm not certain if I'm missing a brass weight that sits on the little ball where the gas comes out of the main chamber with the float. Should there be a weight there on this model? Second, if this weight is supposed to be there, does anyone know the size this is supposed to be? I know it couldn'tbe more than 1/8" diameter, but I need to know the length. If this does not make sense, let me know and I'll try to explain better.
