I just purchased the Magnum 52 for my UltraStick 40. It has the parts to either set up with a standard needle valve direct to the carb or a remote needle valve set-up with the valve behind the engine. This is my first build (I'm a real noob), so I don't know much about this. The remote valve seems to have the obvious advantage of being about to tune without chopping your fingers off, but are there negatives? Can this cause performance issues with inconsistent fuel feed because of the section of tubing between the needle valve and the carb?

Thanks in advance, guys. You're always super-helpful.
