Get#2 cyl a couple degrees before TDC on comp stroke & stick a bar in crank pulley spoke & rest other end of bar on wood block at the right height on rh side.Having piston in that position should stop bar from flying around the other way.When you put the air to the cyl,have a valve that you can open slowly until cyl is up to pressure.If a valve is leaking,you will hear air coming out tail pipe or carb.If a bad ring/s or scored cyl,you should hear air blowing out filler pipe.If leaking into cooling system, you should see bubbles in rad.
