I don't know what will fit your engine being I don't know the neck size and choke size of every carb out there... But I would suggest measuring the choke and neck size so you at least know what you're looking for. I don't understand, however, what the problem is with the Dynamite carburetor? My Mach and SH engines have superb Carburetors. (SH makes engines for Losi/Mach/Dynamite, XTM, LRP, etc..).
