Re: Float Needle
tbwi, if fuel leaks from the carbs when you gently squeeze the primer bulb, the needles are not functioning properly. My Merc 1500 needles have some neopreme (or some type of rubber) on the tips, to help them seal against the brass seats. if yours leak, inspect the condition of th seats and their gaskets and the needle's tip.<br /><br /> Usually at high RPMs, the motor is less affected by the leaking carbs, however if the carbs flood at low RPM, it can foul plugs which means no power to accelerate.
