Hello all just signed up here ,, I been building a giant Spad,, have converted a Ryobi 32cc that came out of a Craftsman blower, run great ,, have built most everything and was doing ground testing making sure it drives good like a car before I try too fly it ,, and well , I grabbed it flipped it upside and it quickly cut right off,, I am assuming its some kind of float problem or something, anyone know what is going on and what I need to do to remedy this? thanks in advance
