Did I hear my name?? Yes I had hydrolock at and early Carlisle adventure, shortly after I got the car. 44IDFs. Racing carbs, so I am told. Maybe jiggered some to allow them to be used on cars that do not race, or do not race very often. The float chamber and carb top are open at the top to the atmosphere. I could not tell you why that might be a good thing. And it will allow water to leak down the throat and in to the engine if things are right, as they almost certainly will be on at least one cylinder. So the Biblical rain at Carlisle, and I got water in there and could not crank it over. Mr. Nichols, and others had been there and done that, and advised removing a spark plug to see if that would allow motor to turn. As I recall we hit the bet (1:4) first time. Pushed the water out, and got going again without a lot of delay. Rain hats followed ASAP, along with a hastily purchase blue tarp car cover.
