1 intake down
2 compress up
3 power stroke down
4 exhaust up
if you start with you start with the piston just a couple of degrees past TDC (top dead center) so that it has started its return down
now set the valves so they are closed:
if you have an adjustable valve clearance's then your clearances should be noticeable like 10 thousands ( you should be able to move the lifter ( rocker arm ) and it will be loose up and down
with the spark plug still out; so you can see the piston coming to TDC and passing it to come down
turn the flywheel and watch the strokes and the condition of the valves
1 just past tdc, the intake valve opens and the piston goes down for the intake stroke
2. jst as the piston comes around BDC the intake valve should close and return to tdc with all valves closed ( the compression stroke )
3 just past TDC the ignition will fire and the piston will return down with both valves closed( the power stroke)
4 just past BDC the exhaust valve opend , the piston travels up and completes the exgaust stroke.
and after completing the exhause stroke and arriving at tdc the intake valve opens and you start over again 1,2,3,4
