I have attached a Tecumseh parts identification broucher that lists models, part numbers and pictures, once you can identify the parts you need just do a google or eBay search on those numbers and see what comes up, the sad part is the parts will be available in the U.S and shipping will burn you if you need a few parts from different suppliers, if you desperately just need 1 or 2 parts you might bite the bullet and pay it but for a handfull of parts you would be better off waiting for another engine to pop up cheap and use it for parts. Gasket kits are cheap and not a problem to source, just make sure you measure the PTO seal as I believe some same models came with 2 different shaft sizes i.e 2 different seal sizes
