Here is a quick check to see if the spring setting on the air valve is correct. If the valve is pressed down slightly to open it, does the engine run rougher. Then push the valve closed by pressing on the end of the stem that is in the air intake above the choke butterfly. The engine should also run a bit rougher. If one way improves the running the air valve spring adjustment may need to be moved to either increase or decrease the tension.
