I did 2 tanks of rich, and then i began slightly leaning it. It worked well. These are very good engines and will be plenty for that stik despite what you hear. I love mine now that i have gotten to know how to use it and fly with it. I reccomend an 11 by 5 or 4 prop for the stick if your into just putt puttin around, but if you want speed then go to a 9x5 - 9x7

This is a great engine when it runs good.
