With spark plug removed, hold finger over spark plug hole and see if you have compression. No compression , engine will not fire on gas or starting fluid! You may have a valve stuck open.
No, if this is two cycle,it has no valves, a lack of compression would be a bad piston/rings. Compression needs to be around 140 psi.
