After a few goes at this procedure I found what I think is a reliable way to set the float heights !??

If you hold the rack of carbs "on end" the floats will not compress the valve springs.
If the hinge pins are a bit loose in their posts a small piece of tape will stop them escaping.
Tilting the assembly slightly brings the tabs into light contact with the pins so you can gauge each float in turn.
I made a plastic height gauge from an old container, a bit like a bridge in shape with a 21(22?) mm cutout.

Basically, that's similar to how I got there in the end. I found it impossible with the carbs sitting on their top side, the floats were pushing on the valve springs and I just could not see what I was doing. I laid the carbs down so the hinge pins were at the top and the floats dangling down. I made a template, 21mm, out of cardboard and adjusted the tab as necessary. After that I checked to make sure both floats were level. Bloody fiddly job, needed superdooper eyesight, loads of lighting and plenty of cuppa's.  ;D ;D ;D

I found exactly the same as Clem, working with the carbs on end proved the easiest way. I used small pieces of masking tape to stop pins dropping out.

I made a template from a piece of an old plastic carton. I think there is a post or a link in a post on these forums somewhere that suggests that.

I also used a workmate to hold the carbs in an upright position. Rest the carbs on the metal frame part then gently clamp to hold in place.

It's like when you peel one of those wee oranges, a stream of juice ALWAYS finds your eye, and it bloody nips too! :D

Hi Chaps
Just a quick update. Iv'e put the carbs back on, after checking the float heights for the zillionth time !!!!. Have adjusted them as far as possible and will now have to wait till I get the rest of her back together before firing her up. Hopefully all should be ok though  ::) ::)
