I'd like to know how many people out there are running large glow engines, such as the st2300, OS 160, BGX, Moki 180, etc with a "standard" fuel system. When I say standard, I mean, muffler pressure, no pumps or regulators, tank near the engine, no check valves, no header tanks, etc. More specifically, has anyone gotten acceptable results by just using large fuel line from the clunk to the carb,(along with large brass in tank)? Acceptable results means that the airplane is capable of all aerobatics, and the engine doesn't go lean or quit in flight. I know many of us are using pumps and regulators to get the tank back on the cg, but would we still want to use them if we weren't concerned about the cg shift? I have my own set of opinions on this, but I'd like to hear from some of you who have done the flight testing to support your comments.

Thanks guys!
