No spark to my spark plug?

Your coil problem, change with the new one.

Possible warped/cracked head or cylinder wall.

Head gasket leak

A good rule of thumb is they have to be over 100psi to start and run. I have found they can be up to 170psi on pump gas.

Change the spark plug, that may help. <div>Regards</div>

Sounds like your oil/ fuel mixing valve may need to be replaced. New gaskets for it at least. Hopefullly your engine gaskets are ok, that's the first thing I thought of until I saw it was a 2 stroke.

Has it been laid up for months? Did you leave any gas in it untreated? You may need to boil out the gas tank . Try a carb cleaner first that you add to the gas.Check the plugs.Are they black/oily (too rich / worn ring), Tan ( correct ).they tell a lot about the condition of the engine. Good Luck
