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.

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.
