There's not too much available for these carbs by way of jets and needles. The float heights are a bit lower at 19mm already. They should be 20mm as stock. Looking through Google this appears to be a very common issue, to the point that several companies sell a complete Mikuni conversion kit. These kits come with everything required but at an outlay of about £460.

You may be correct there. Problem is that over the 2 years since it was finished I have tried all sorts to lean it out a bit. Any changes just make it run badly. I get the impression from the internet that these CV's are just rubbish carbs. They were probably okay new but 50 years of wear hasn't helped.

I would have thought the lower the float height, lower fuel level in the bowl. the lower the corresponding fuel pressure to the main jet so the leaner the mixture.
