hi guys thanks a lot for the help so far the engine is running better the more I fly it and pick up another 300 rpm still with the old sh*@% MA prop . But know I have two other problems: 1st the carb sprays quiet a bit of oil inside the plane, what can I do to solve that? and 2nd I can't get more than 13 ~ 15 minutes with my 24 oz fuel tank (already got 2 dead sticks, run out of fuel) is that normal? what size tank should i put in?
