Thanks everyone for your help.
I live in Geelong VIc and the mower is in East Fremantle WA the elderly owner is very capable in maintenance and he has fixed everything and knows the flywheel is not working in fact he wanted to re magnetise it but could not find anyone who could help. The mower is for mowing as being so light he can manage it plus it is the only mower he has used. Unfortunately he is not into computing hence where I come in. I also know the difference between a screwdriver and a hammer. I am happy to purchase one then send it to the west. Also I have a place in Cootamundra NSW if that location helps.
