Scott-oiler
Without disputing what you say, I'd like this discussion to stop. The last thing I want is to be forced to confront the fact that what I really have is a persistent leak into the kick-start cover from the gearbox. Particularly when I've fixed them all. Or from some other source, by devious, secret, means. So if you don't mind, I'll continue to put off the evil hour by playing with the Scottoiler (which delivers oil just where you describe).
The real genius of PEI was in ensuring that oil that leaks from any part of the motor manifest themselves somewhere else, somewhere remote, somewhere oil couldn't possibly travel to, thus ensuring that bonding between man and machine so necessary blah blah blah...
