Hello,

Ok, did this happen all of a sudden?

What color is the spark? It should be a Bright Bluish/White.

If Orange spark is weak and will need to replace Coil.

Ok, what color is it at the plug?

If Orange or no spark at all, remove cap and look inside check the eletrodes for corrossion. If corroded clean them up as best you can along with the tip of the rotor. Put it back together and try starting it if it starts replace cap and rotor.
