Oil leaking from under carburettor

Does anyone have any ideas as to what could be leaking there it's dripping down onto the diff but is coming from high up near the under side of carburettor I have another leak which I think is the oil pump where the pipe connects with the copper washer and then they is one near the transfer box all the oils are thin and dark with no strong smells if anyone can advise me I would much appreciate it I'm new to landys I know they leak alot but just want to get the jobs done so I have piece of mind thanks
