Glad I took the time to read through this, as I'm about to make a similar test rig. In the same vein, my float bowls do not have drains but I like the idea of setting float level via the tube out the bottom of the bowl method (dynamic ?) rather than with the bowls off. Are the drain type vs non drain type bowl inter-changeable on a 930 carb?.............sorry to go off topic but

Sounds like a simple enough question to get a quantitative answer to since seattle##gs has made the test rig and can easily test gas, alcohol and water at a fixed float setting. The only comment I’d add is that carb bodies are typically contaminated with sufficient residue that water does not wet well on them (water can bead up and does not wet like gasoline on oily and contaminated surfaces), thus a drop of surfactant (dish soap) in the water is necessary to lower the surface tension of the water so it readily wets the gas line and carb components. Before running the experiment be sure to put a drop of water in the carb bowl to assure it wets, otherwise you are introducing another issue that you don’t want present in your experiment.

"Sleepless in Seattle" waiting for seattle##gs to complete the fuel level test with the 3 fluids. Did you or other contributors with test rigs ever try the 3 different fluids to quantify differences in fluid level at a fixed float setting? In the mean time perhaps I'll just think about Meg Ryan in Seattle.

I am going with the sure thing and continue to use gasolineand use a small fan to blow the fumes away from me. This method with the fan also works well if you are chopping onions. My eyes have become very sensitive to onion fumes and this solves the problems
