G'day Nigelmort,
Here are some PDF downloads.

The operators manual for that engine: http://bsintek.basco.com/MDEXResultsPages/PDFDisplayPage.aspx?fileName=flmvtLX-nfBhU7y

You'll find the part numbers you need in the IPL; http://bsintek.basco.com/MDEXResultsPages/PDFDisplayPage.aspx?fileName=18jsBLXBnfBhU7y

Be warned, those bits are quite exy for what they are, as I doubt that there is an aftermarket source for them.

Cheers,
Gadge
