Thanks!
10% Powermaster fuel and we are at Sea level. If you are at a higher altitude, you may want to use 15%. No pumps, the fuel tank is installed at the stock location. We tried a 20x10 but is a little too much for this engine, even though they advertise a 25lb of thrust with that prop. With 19x8, you get awesome RPM transition and yes that prop is awesome and that is why it cost $40.
