Try a valve lash of .031". That will help some. The engine will run good with the exhaust beginning to open 10-20 degrees before BDC and closing at or very slightly before TDC and firing at TDC. (fuel: Coleman or other pure fuel or white gas mixed 15:1 with Marvel Mystery Oil)
Best of luck and have fun!
