the engine is a beauty. has ran well for over a year, moved it to the new plane ( Harmon Rocket 111) Had to turn it 100 degrees on its side , as per intructions. now the problem i have is the the needle setting of 2.5 turns is ok . and can lean it out. but i can turn it anti clock wise and it still runs. tho very rich. i can undo the needle till it nearly comes out of the housing. What have i done wrong???????????????????????????[:@]
