I have thought. about trying to do this also. I havent seen anything like one on the market anywhere. I dont see why one cant make a manifold to screw on to the exsiting manifold that would put the carb where you want it. I kind of like the carb in the back as it makes the whole unit more compact but it sure is a pain to work on. the stock carb location really makes it tough to get the throttle arm to work right.
