I finally got it running good today. the valves were way out of adjustment. one was tight and one was at about .020, i adjusted them to .004 and it runs great and starts easy without the choke. i just put my finger over the exhaust flip the prop 4 or 5 times hook up the glow starter and hit it with the starter and it starts right off. Its running full throttle at about 9,500 rpm with the 15x6 prop and idles at about 2200 rpm. I know the prop im using is quite large but i have the engine in a bud nosen trainer and the fuse is about 8 inches wide so i have to have a prop large enough to get around the sides. Also thanks for the instruction manual it came in quite handy.
