I want together my motor closed up today but can't figure one thing out. When adjusting the valves on any cylinder do I want those cam lobes to be pointed up or down? My manual seems to say to adjust them with the lobes up but I think I am reading it wrong be ause then when the lobes are down there would be a lot of lash. Then again if I adjust when the lobes are down, when the piston comes back up the next time would the valves be open a little?
