well i richened up the low like suggested in previous thread i made a couple of weeks ago to whee the throttle response was slow, i redid the tank. and im still having the same problem, i can get it to purr like a kitten on the ground....then when it comes time to land i chop the throttle and its "idling" so high it is still flying. Ive never had this problem in my whole life im willing to pay for a carb that will work
