Hi Norm,
Well I've had 3 in a row now as you probably well know, but I guess that's why these mowers all eventually hit the disposal list and get put out to either hard rubbish or scrap metal. Replacing a coil via a mower shop will generally be over $100 and with a few other things that need doing to each machine it becomes all too much in the end costing, so a new mower is purchased from Bunnings or one of the backyard retailers that do most of this work far cheaper.
Cheers,
BB.
