I am working on a House of Balsa A-T6 Texan, and am at the stage of hooking up a fuel tank. Since I don't have room for the muffler - I am trying to hook up the fuel tank w/o pressurizing the tank. My question is --- Do I have to vent the tank, or will I be O.K. with just the carb line???? This is an older Enya 15 engine. All F/B is welcome. :drowning:
