i have a tower hobby-46 and its mounted inverted and the problem is fuel keeps dripping out of the carb, when i lean it out it dies when i hold the plane straight up, it smokes alot and sounds like its really loading up. what could be the problem? the plane was running perfect last year. i have tried adjusting the settings but just cant get it to stop flooding the motor. what is a good setting to start with? could a air leak do this? thanks for any help,, Larry
