Thanks for the replies, I drained off about a litre thinking that would take it below the correct level & it took it to right on it !!
Then with the help of gravity & a wobbly trestle, I spread 3/4 of that around the garage floor :wasntme:
It looks like it was a simple overfill but I'm off down Gippsland on Saturday so I'll clock up my first decent trip. Hopefully the problem was a simple overfill..
