I swapped carbs around and the problem is following the carb...so at least I know were to look. These are bloody brand new carbs.....wish I could send them back.

I pulled the offending carb off ,throughly cleaned it out with compressed air
and refitted with no change. I don't know what to do now. I thought I was dealing with a vac leak but now I think I have a dodgy carb.

I have a centre pull linkage, works well.

That's good in way that you have proved it is a carb problem.
Better than a manifold or cylinder problem.

It does seem odd if you have blown the passages clear and can't see the reason, I'd strip two carbs and do the same compressed air test on both, I'd also blast some fuel through the passages so you can see the flow discharge.

Swap the idle jets between carbs as well.

Don't get fuel in your eyes, it hurts like hell.

If none of the above helps, take the offending carb back to your supplier and see if they can help you.

Cheers for the help.
I bought these carbs a year or so ago and just left them in my closet at home.

The carb behaves like it has a vac leak but nothing I do changes it's behavior.
I have 2 good carbs ,one half working carb and one dead carb.

I have swapped jets, swapped floats, you name it. EFI was so much easier.
