I thought the trouble with the Carb is the probable venturi freeze if it was
flowing water. A problem injected does not have. But thinking and knowing
are differant. Not betting the farm. Just clarifying ideas.
Takeoff is the critical point. Something I have never seen discussed is
knowing how long it takes for water to effect your engine. It would seem
that one could introduce water in the fuel and run the engine up, and time
how long till the engine sees it. Assuming this was well known one would
think that run ups on the ground for a longer period than this would be
excellent prevention.

I suppose it should, but it doesn't. The same scenario would apply to
carburetors. If you windmill long enough the water will pass through
the system. Part of the issue is that water has a nasty habit of
rearing its ugly head right after takeoff when you really don't have
enough time to crank it all through the engine.
It could work, it should work, but it doesn't work. Don't bet the farm
