Lawnmower - for spares or repair (Southport PR9)

Hi, my fantastic Bosch lawnmower decided to stop working this weekend - again. So I've bitten the bullet and bought a new one. I had stripped it last week and took a load of muck out of the inside and thought I'd got it going again - but then half way thru the weekend mow it failed again. It may just be the starter switch or the motor may need a tinker but that's beyond me. So if you can repair or make use of parts it's yours. Otherwise for the tip!
