Hi MrMckay, thanks for the reply

Haven't gotten a list yet, but hopefully it won't be big. So far it's just a piston(+rings) and gaskets I need to pick up. The muffler 'might' need to be replaced if I cant repair the split, but so far, still dismantling/cleaning parts, then Ill lay them out on a table and see what i've got. Haven't got around the the carb yet either

.. hopefully that just needs a clean.
Im from NSW too, but yeh, postage I think will add up. Roughly how much would you say a 2nd hand piston (in good condition) would go for compared to a new one ? That's probably my primary item for now.
Oh, and just wondering, what do you guys find to be a great degreaser for cleaning the parts? I've used "Koala Kare RTU Degreaser" (from supercheap auto), but seems a bit slow/weak on the harder grease/grime.
