Which timing are you referring to. Spark timing or valve timing.
Spark time is fixed and controlled by the crank trigger. Theres only two thing that can change spark timing. a twisted crank ( very rare ) a sheared flywheel key (Also very rare)
Valve timing, remove the timing inspection plug and the the pull start housing, you will use the nut on the crankshaft under the pull start to turn the crank to bring the timing mark into the timing inspection hole. remove the spark plug so your not fighting engine compression to turn the motor.
Now remove the the valve cover and check the alignment line on the cam. the alignment line should be level with the top of the edges of the cylinder. if not you have a problem.
