I have a .21 hybrid that I received new from Glenn. It replaced a NR 5p,.

I have not been able to really get this engine to perform much better than the 5p,.. Any suggestions on changes that should go along with running this motor?
 
188° exh,30° blowdown,.19 cc head volume with .007 head clearance,open the crank about 210° to 215° ,close about 65°,make sure you let it warm up(water).with the right prop and pipe this will get you to 75 to 80 mph
