Hope you haven't spent too much on parts Geesey as last summer I sold two newish serviced mowers for $100. each ,one was 3 years old and I think it got thrown out because it needed blades and the 4 year old Victa had a rusted out base that I replaced.
People around here mostly don't pay for repairs and I think just buy new mowers from Bunnings.
The biggest mower / machinery shop here that started in the sixties closed down this year.
I spoke to another mower shop owner who closed a long time ago and he said sales went down hill after Bunnings started selling mowers.
I wouldn't be surprised if the coil needs replacing , I've had new coils out of the box not work from eBay, also had a lot of newish Chonda coils that needed replacing.
I try to not pickup free mowers these days but it just seems such a waste for them to end up as scrap metal when all they need are blades or a service ,especially if the mowers are only a few years old.
