Lean mixture, set your high speed jet a little rich. Adjust when on full throttle and warmed up. Turn in, lean, until speed slows a little, then turn out, rich, until speed slows a little, then turn to the middle setting. Then adjust a little rich. Put engine on idle for a few seconds, then put to full throttle very quickly. Engine should speed up with out any delay. If it stumbles abit, then set the mixture a little richer, until it's good. If it does not work, you have other troubles. Check setting of points also. Noel.
