If you remove the spark plug and ground the plug, do you have spark? With spark plug out, put finger with rag over the spark plug hole and see if it has enough compression to move your finger when cranking. If it has spark and compression, put a teaspoon of fuel into the spark plug hole, re-install the spark plug and see if it will fire for a few seconds.
