Hi All !
An update :
I did some tests with the float
It floats quite well in water , but not with gasoline - something everyone probably knows - Although testing with gasoline does not have the weight of the check valve

I reduced the weight of the float and tested again with a weight of the check valve : all of them float quite well in gasoline

Next step : I will design a carburetor according to the test and when machining the float I will make it lighter
