I setup mine with a fuel dot on the side of the Cowl. Using a 3 line system - 1 to carb (with clunk), 1 to muffler (vent to top of tank) and the third (with clunk) as the filler to the fuel Dot. Works Great. Only thing is it can be a little messy as you pump in fuel until it comes out the muffler. Have not had any issues with flooding of the engine.
