You will need to take the blower housing off the engine first .
Then probably remove coil.
Remove screen , bolt / nut holding the flywheel on . Will need a puller to remove flywheel . There are different tricks to removing one but a flywheel puller is the saftest way .
LUCK

Hi,
In the face of inadequate tools, I will loosen the flywheel nut and back it up to near the end of the crankshaft, place the ball-end of a ball pein hammer on the crank and strike the flat face with another hammer. The shock effect will loosen it in two or so blows.
Peace,
