Scrambler no spark under compression

I have a scrambler that has never ran on the New piston. 130 psi compression. Piston is racing right way. New reed valves. New plug. Tried 3 New plugs. Getting spark. Flywheel key is fine. Carb was cleaned. Plug gets wet every time I try to start it but doesn’t try to crank.. So confused. What should I do?
