PW50 fires but won't start

[Nate]

i have a 2004 PW50 has been running good for years then one day my son said it stopped running. Put new spark plug in, cleaned the carb(4 times), compression is 110 psi, has spark when testing spark with spark plug close to motor bolt, but is is enough spark? When i kick it over it will slightly fire but won't start. Tried a new carb and that didn't do anything. Could it be the stator, ignition coil, ignition control box or CDI box?? Has anyone ran into this? 

Thanks
