There's no issue with the engine drawing fuel with the tank underneath the engine. I have done some testing with a fuel tank 6" below the engine and.3" behind it and the engine ran well. You have to compensate with the needle settings a bit. Lean runs happen because of improper needle settings. The FP engines have tiny Carburetors, so they draw fuel well. Other than fuel siphoning when the engine isn't running, there should be no other problems.
