What's the best way to hook up a remote needle valve? The valve has one fuel line fitting on the end opposite the needle, and one coming out the side at right angles to the needle. It would seem to me that the line from the carb should go to the fitting on the end. That way, any suction from the carb would not act on the needle threads, which might allow air to leak into the fuel line. Problem is, the picture on the K&B website shows it the other way (its a K&B 61). The flow would be the same either way. Its sucking in air I'm concerned about. Any opinions?
