you are following guide on page 2 no 6 down set no3 etc ,and watching carefully so that it just reaches fullest compression of spring and no further then check,the other way is to turn engine till valves on 1 cylinder are rocking one opoening and one shutting both under compression the if thats no 4 cylinder set no 1 cylinder pair ,no2 set 3 no3 set 2 no 1 set 4 ,this is because 1and 4 are at the top at same time while 2 and 3 are both at bottom if one of pair is just finishing compression stroke the other must be finishing exhaust stroke so both valves will be sligthly open one shutting the other opening the other cylinder must have on compression stroke and power stroke both valves closed
