Hi Millzy, if it is a mower you want to use and keep, not for a collection, you can't go past a sorted Powertorque, once the problem bits from the carby are sorted and it has a good float needle these mowers with a bit of maintenance can be used way past my use by date. Biggest problem with them is the carby ( most usually the float needle) that sent millions to an early grave and the next thing is wheels/bearings wear out,or the base starts to rust out, people sort of put up with it for a while and once a wheel falls of they chuck it, but in 90% of cases the motor will still have years of life left in it, and worst case scenario give it a hone and put a set of $10 rings in it and it is good for another 20 years or more, and give it another freshen up then.
