Tmoth4 ; Did you weigth the motor without the muffler ? I changed the muffler to a j-tec make sure you use the primer bulb and it is installed to draw fuel from the tank through the carb then into the bulb and back to the tank. If it is wrong it will not run or idle right . What plane are you planning on? I think you will be very happy with this one. Keep me posted... :surprised




Ps It pulls my gee bee great.
