Water injection cleanup?

My wife hasn't given me my "honey do" list yet so I have a few moments of an idle mind. Just thinking. Would it be a foolish thing to use a squirt bottle to squirt water directly into the carb. air intake on a fully warmed up engine. Seems to me that the water when taken into the cylinder would make a surge of steam that would clean up the cyl. head and valve area. Remembering the old water injection system used on old CB17 aircraft engines. What do you think? Do I just have too much time on my hands today? I was thinking of trying this but do not want to damage my engine that is NOT broken.
 
I believe that a kit was available to add water to the fuel mixture. Seems that the advertising for the water injection talked about "Remember how smooth you car drove after a rain ?"

By the way, my car does drive much smoother after a rain.

That's because the rain freezes in the potholes, so the road is smoother.:D

I could be wrong, but I think the aircleaners on the old Fordson tractors pulled the air through a water bath!
 
I am still wondering if some of you engineers can tell me if my thinking has any merit. Would this work?- is it totally useless?-- is it harmful to a low compression "A" ? engine?
Also in response to engines running better after a rain. I have heard this all my life, but in reality, if I am not totally deceived, high humidity air is less dense than dry air and therefore will actually reduce power output.

Frank, Model "D" John Deeres used water injection to stop pinging.
A friend, Frank also, installed an Octa-Gane water injection system with a button under the throttle, controling a solenoid valve to stop pinging in the mountains on his 460 Cu. Inch Ford Camper Special.
I've had good success using water in the carb for de-carbonizing, especially in cases of detonation/pinging/dieseling. CHANGE OIL AFTERWARDS as sometimes "milkshake" in the oil happens from doing this! Bill W.
 
I have done it on more modern engines when they had been running too rich. My grandfather told me they used to do it back in the old days to decarbon engines. You have to add it slow or it will stall. I try to keep the rpms up while I do it. You have to be careful not to add it too fast or you can hydro-lock the engine and damage it. You can also do it with MMO or Sea Foam by slowly squirting it in the carb, but water works best for dry carbon buildup.
 
I have misted a Model T engine and try it. It seems to work. But you just want to feed a mist not a flow.
 
Tom,

Yes, here in the "frozen tundra" of the North country, pot-holes are only around for the two week summer. The rest of the time the water freezes over them !

In my '71 F100 with a 460 ci engine, I use to "force feed" it a glass of water everytime it started acting up like this. It was good to go for another 5K miles or more.
 
I poured Sea Foam into my motorcycle engine-VERY SLOWLY and ti belched white smoke. After awhile it cleared up and ran fine.

Auto shops used to pour water down the carb before a tune-up, to get rid of the carbon. It worked then and will now. Keep the revs up and pour slowly. It will be more difficult with the updraft carb, a squirt bottle might be best? Paul from Main ... tractors, trucks and many cars used an oil-bath air cleaner where the air was forced into a "U" turn and dirt embedded itself into a pool of oil at the bottom of the cleaner. A simple centrifuge.
 
Steve,

Yes it will work it's an old mechanics trick to do just as you were asking about.
Watched my Dad do this many times but as others have said get a glass of water and slowly poor it in with the RPM's up. You will be playing with the throttle keeping the engine from stalling while you are pouring the water.

I want to thank you all for your replies. Many were to the point of my inquiry and I appreciate it.
