Thanks for that update, Peter. So far as the pressure washer is concerned I suggest you avoid buying one that is cheap because it has pump problems - if it has scoring it won't be fixable, and if it needs parts they may not be affordable.

I haven't had anything to do with modern Rover frames, but the old locally-made ones were quite good. That chonda engine should last better than a Briggs, provided it gets any small repairs needed along the way. Incidentally an Outdoorking member, roebuck, has accumulated more experience with repairing chonda engines than anyone else I know, and is likely to be able to help if you run into strange variations in the design of chonda parts. He even has experience in obtaining spare parts for them.
