I just thought of something...Doesn't the carb spray only what's needed to the motor? Doesn't it have the last say how much fuel goes into it (I don't mean of it doesn't get enough fuel flow)? So shouldn't the setup work well as long as the pump delivers enough fuel? The fuel still goes through a tube before it gets to the carb and from there the carb regulates it. So why are there problems of it getting too much flow and having to turn the needles way down. Doesn't that mess with the air/fuel mixture ratio?
