Hi guys,
Does anyone know if there is a difference other than the orifice sizes and float valve between these three carbs. (439380, 439377, 439378). Ive done the research and all three carbs come from a mix of years and engines sizes from 25-35 hp. all have matching part number for bowel, gaskets, carb cover, fittings and ext. They look the same but I'm not sure if the body is different or if the venturi is different between the models.
