Near impossible to hold the carb 100% perpendicular so I took the mm-accurate settings with a "margin of error" . .

Had a look at this today and sadly not that applicable to the above drawing. The main reason is the float is not a uniform round object, it is a complicated shape and hence not convinced the above is the correct setup as hard to judge where to measure to.....

Peter,

Just try to get the top flat surface of each float half parallel with the carb top cover face and adjusting to maintain gap between 7.5 and 8 mm before gasket.  Gasket will be just over 0.5mm, say 0.5mm when top screwed down.

If the spring loaded damper ball in the needle valve is not too tired then this should support the float even if carb top cover fully inverted.  Before fitting gasket and re-assembly I just concentrate on getting each float half set similarly with each float top surface parallel with carb top cover face.  I do this by eye and when I have measured it comes out at between 7 and 8mm (i.e. before gasket)

Have just split my spare carb - working OK a few weeks ago and measured float height  ......

Where did that come from?
Finally a float level specification in print.

Hi

Thanks, I will look at the floats I have which I think are a different shape, hence my comment. Yours are flat on top which makes for easy measurement.

Just to add to the debate then see that Eurocarb quote float height of 7.75mm/8.25mm with gasket

It came with a refurbishment kit so I think I need to give credit to Ricambio who supplied it, and answered a few rookie questions from me. Good service and happy to recommend

Peter

I checked on my float and sure enough it is a replacement I had as part of a kit and it is different to the Weber original which I also still have. the Weber is flat on top, my float has a small bulge on it, approx 3-4mm high. I therefore measured to the main body and set accordingly. So far with limited test possible it is working ok.
