anyone know what Carb options I have for a briggs 4hp Vanguard OHV ? would a mikuni work? I compared the briggs carb to the clone carb and the bolts that hold it on are in a diff place. one side by side and the other canted at like 10 oclock and 4 oclock. (hard to explain sorry). Just looking to up grade. Thanks for the help. ( as soon as I get a "classic" engine ie. tec or flathead, I will replace the vanguard. Its an older one prob 6 years or so).
