Thanks Grumpy,

So it is the bolt I have highlighted ? The head is actually hex and there is one on the other side(back )as well as another plastic oil level plug.

I found the oil I need in my shed,Victa Formula V 4- stroke high performance engine oil which is SAE30 mono grade oil designed for Briggs and Stratton & Tecumseh Engines. I already use this for my Victa Tornado.
Any Idea what the manufacturers specified capcity is ?

Any Idea what one of these might sell for. One went on ebay recentally not working for around $200
