Scorpion Pressure Washer

[ozm29c]

Fellows,
Brains trust question: I have one of those El cheapo (Chinese I believe) Scorpion petrol engine powered pressure washers. Got it from Repco about 7 years ago. Surprisingly it has given me a good run but unfortunately I now need to replace the lance pressure Nozzle. I have been searching on Google (with no success ) for an online parts manual and more importantly a spare parts supplier. Most retailers like Repco only sell new washers. Apart from buying a new pressure washer, any thoughts/ideas/experience with regard to these washers will be gladly accepted.
Cheers in frustration.
