Thanks Mark, from your experiences and one or two others in the archive, it seems they are a bit sensitive. I'm hoping we will learn something from the float height or main jet size.
It is interesting to see the wide range of main jet sizes listed in the manual. It is especially interesting that it looks as if the less emissions-regulated the market, the bigger the main jet. I also remember one of Suzuki's popular cars which, in Australian emissions format, was prone to surging (the equivalent of a governed engine hunting) rather objectionably at some intermediate speeds. There could be a pattern forming here.
