ok kohler guys, i am playing around with an idea, and i need some advice/part#'s. i want to know which 1bbl carb with the throttle blades opening on a horizontal plane, and with the bolt mounting pattern that is NOT straight across from each other( they are diagonal), you like best. i have looked around alot, and have seen many different ones, and would like to know which one is preferred for racing, and what part# it is. you can also pm me with your advice if you like, thanks- Jim.
