I recommend getting a side exit fitted to the exhaust of your Morgan. I've just had that done today and it makes a great leaf blower.
I'm looking forward to seeing a video clip of that in action.....
Well, the leaves are starting to come off so I'll see what I can do in the courtyard in the next week or two. Watch this space. If it's really bad I might have to get somebody down with a Plus 8 and twin side pipes!
