Bear with me, I'm new to this, and am a novice! I'm better at cutting grass than repairing my machinery! I have an Atco 28" mower in decent shape but it has a weak spark. I've been reliably informed it is because it needs a need coil, (possibly condenser as well?) ? I've started to take it apart and have got as far as the picture below. I want to remove the flywheel to get access to the ignition system and check all the components and fit a new coil.
Before I get my lump hammer out and start smashing spanner ends - can anyone tell me how I get this flywheel off?
Thanks in advance.
