Ralph, As far as I know, there are no nice looking stacks available for the current series of large-inlet Tilly carbs. EC Carburetors makes machined stacks, but they have a cylindrical outside diameter in order to attach a filter element. They ain't pretty, but they ARE efficient. You can dig around in their on-line catalog, but it's a clumsy affair and hard to navigate. TJ
