When working at a parts house a few years ago I got a really good discount on them and have ran 3 of them.....no problems. Maybe I'm the lucky one????
Martin, not sure it will help but I have a book that came with the last one and it has details about switching jets/rods along with a C/D that may help you straighten your carb out. They are really fairly simple. If you like I can ship them to you for review. PM me.
