Can not turn the flywheel?

1. where is the ignition unit?
2. i removed the spark plug....engine still, will not crank...still frozen flywheel
3. HOW WOULD I LOOSEN FLYWHEEL IF FROZEN.
Are you saying that something is lodged at/in flywheel area
preventing same from kicking over?
Today I observed the starter trying to move the flywheel, but, to no avail.
Any additional help/comments..thanks

If it was running fine before you serviced it, it must be something you have done, is the flyheel rubbing on the ignition unit? have you dropped a screw somewhere? have you put too long a screw into the blower housing which is now touching the flywheel? have you put too long a reach spark plug in it that is now touching the piston? have you over filled the engine oil? remove the spark plug will the engine now crank? is there fuel/oil above the piston?
