2 Strokes Down Under

I reckon I'll give them a go, can only leak oil, or suck in a gut of air and lean out, blow up like it did on previous owner!

There is some repo gasket kits on abay at the moment, seller is cruzinimage_au & cruzinimage_uk they are about $45 a set plus freight.
Dunno about the quality or anything.
Has anyone tried these?
