Hey J, got the engine out, cleaned up and ready to turn a prop. Looks like the motor is 21cc[:@]. Dont know if it can make enough power to offset its weight. I'll find out but dont hold your breath. If your looking for a good little powerhouse the homelite 25cc is hard to beat. You can most likely get one gave to ya and they make great power on the stock carb. Im flying a 15lb plane with one now and am really liking it. Piper
