There is an intake and an exhaust stroke. Both are at TDC. One of the has the valves tight and the other one loose. Rool it to TDC again to change the stroke and see if they loosen up. You want to adjust them when they are on the loose stroke.
EDIT: This is from my manual. It may explain better.
Rotate the crankshaft using the recoil starter knob
to align the ‘‘T’’ mark on the flywheel with the index
mark on the rear crankcase cover.
Make sure the piston is at TDC (Top Dead Center)
on the compression stroke.
This position can be obtained by confirming that
there is slack in the rocker arm. If there is no slack,
rotate the crankshaft one full turn and match up the
‘‘T’’ mark again.
