If you have a bent valve you should notice a miss at idle. Locate the
missing cylinder.Raise the piston to top dead center.Remove the valve
springs and let the valves rest on top of the piston, rotate the valve stem
and if it is bent you will see the valve rise and fall as you turn the
valve. A good mechanic can do this. He may also put air pressure to the
cylinder and do a pressure test.etc. When he reinstalls or removes the
springs he may have to put air pressure to the cylinder to hold the valves
in place. Check all the cam lobes for wear. In some cases you can race or
goose the throttle and if the cam has a flat or worn lobe you will hear a
slight backfire noise at the throttle body if the air filter hose is
removed.
