First off you will need a 12v power supply for a timing light that is capable of being set for a 2 stroke as many are not,then you need to mark the rotor, how are you using the degree wheel while the engine is running to check spark timing? with the rotor marked and engine running you can then use the timing light to see the spark timing and that's kinda hard to do when it doesn't start!
