I'm an old motorhead. 83 yrs old to be exact and I was using this method when I worked at a Pontiac dealership back in the early '60s. Yep, it works! As a matter of fact there would be carbon blow out of the tailpipe that you could feel and see. The only thing a person has to be aware of is that some of the carbon can become lodged on the valve seats and cause a temporary misfire on some cylinders. This will work itself out with a short drive. I've had some engines that would not idle after this procedure until after a short drive to clear the valves again. Thanks for keeping this old "fix" going.

When I was a kid in the sixties my mother started up a hill and her car sputtered and quit. It just happened to be in front of a country garage. The mechanic and his sidekick came over, listened to the car, and the mechanic asked his helper what he thought. He said 'I think it needs a drink of water' and I thought 'what the hell'. He came over with a coke bottle of water and poured it down the carb while the car ran and the car stopped skipping and began running fine. I've never forgotten that.

Back in the early 2000's I had a Chevy Astro van that was missing on one cylinder, I took it to a repair shop and they told me that it had a blown head gasket on that cylinder and that it would cost around $1000 to repair it. As I was leaving shop one of the guys that I had known for years told me that it was not the head gasket he told me to take it home and run ATF down the air intake and then follow it up with water. I ran close to quart of ATF through it and then a quart of water. After a short drive the miss went away. I drove that van for another 5 or 6 years and it ran great and it never missed again.

I'm 63 and been using water to clean the carbon out since I was 15 works great

I'm 75 and my dad taught me this trick when I was about ten. We used it on tractors and farm equipment. I still use it on older cars. Thanks for the refresher

[petergrey]

Thank you for teaching us these old-school tricks that almost nobody talks about anymore.

I watched my daddy and his brothers do this when a car was running rough. It smoked a bit and leveled out and idled great. I miss the old carburetor engines. Simple and easy to work on.

WARNING: Tesla vehicle owners DO NOT use this method to improve the operation of your motor. You could get SHOCKING results!

How do the Same thing on Newer Injected & Diesel Motors.??
This is EXACTLY what I’ve been talking bout for decades now to get people to do & “COMMUNICATE” by passing “LIFE” Down before it’s Gone!!

THANKS FOR SHARING !!
Keep it up !

My dad was a B36 mechanic in the Air Force. Those six big radials on that plane used water injection for keeping them clean inside.

I am almost 80 and what we did in "the olden days" we would run about 5 quarts of water mixed with a bottle of 3% hydrogen peroxide. Get the engine hot and run this through a small vacuum tube into the intake at idle. The water would react with the hydrogen peroxide and burn the carbon off. I used it in my 40's cars to my 426 hemi drag car. I am about to use this on my Jeep and Furd F-150 eco boost. I relate these old time fixes with the old timers using natural trees and flowers to aid aches and pains compared with aspirin (same remedy you get from making tea from Aspen bark. Don't knock it until you try it.

Im 149 years old and been doing this since 1875 works great !!

[davetherave]

I used to do this on my cars back in the 70"s. I even installed the "Ol" JC Whitney water injection kit, (back when it was mail order). The complete kit was a Mason Jar with a valve on the lid (adjustment) a piece of hose and a T fitting for the PCV. Thanks for a ride down Memory Lane, Brother.

My Dad was a Navy Aviation Mechanic in WW2 and Korea. He shared lots of Old school tricks of the trades with me. All good proven practical methods!

[fordgalaxie]

It's awesome that you're sharing this I'm 64 and I learned about this from older guys when I was a teenager

In the 60's i worked At a Chevy dealer . These were the days of leaded gas and low compression engines. We used to get older folks that came in with bad carbon knocks in their engines . They thought they had bad engine problems. Our mechanics would take them down back and use the water decarb treatment for 10 minutes and come back running like new !

I am 57 and been doing this since I was a kid in the 70's to lawn mowers to make money doing Tune ups at my dad's shop, spark plugs come out perfectly clean, re gap them and carry on.. Then in the 80's when I became a certified mechanic and all the "snake oils" came out I just laughed at the salesmen who would try to sell me their junk., and grab a bottle of water and show them how much better it worked . Potato water works even better.

[chrisguerra-swlf]

My father taught it to me when I was 11 years old. I remember laughing because I thought he was fooling around dumping water down the carburetor. He passed away 2 years ago, and I still smile every time I see a video like this.

[TonyMontana-wtbu]

He's telling the TRUTH. I was taught tricks like this by my late uncles and it works 💪.
