    what mods do you have or what is done to your engine? These things need to be known for you to get the help you need. I will say, those small bore carbs work great with restrictor plate engines in kids classes, but a .615 clone carb is better for adult unrestricted classes

    So you have the stock muffler also or is the weenie pipe allowed? most likely the stock jetting is going to be what your engine runs best with, unless you can get a 30 main and .022 low speed jet to work with the stock airbox and muffler
