Wet sumping, singles?

[Mharrisbarton]

I think that I know most of the causes of wet sumping in single cylinder ariels ? but I would like to ask members for their thoughts on this subject to ascertain what I think I know, or what I have missed! looking forward to seeing members comments. Matt Barton.
