When the piston is at the top of it's compression stroke both intake and exhaust valves should be closed, or there wouldn't be any compression. Put you finger over the #1 hole and when you feel it push your finger off, you are at the top of the compression stroke.
 
...replacing the cam shaft and crank? So I lined up both timing marks and am trying to set the timing. and seems like maybe i put the crank shaft 180 off crank shaft is half the size of cam shaft. At what point of the # 1 valves going up and down should the cylinder be at TDC to set timing? I watch the valves exhaust opens closes intake opens and closes at that point #1 cylinder is at the bottom not the top ???? does that mean my crank shaft is 180 off?? Any extra info would be appreciated. When I try to start it it is forcing itself to turn over, pull the plugs out and it turns easy I have a fully charged battery
