Decarbonize engine
I have recently corrected an extended issue of an over rich carburetor. Now I would like to decarbonize the engine. I was watched videos of using water down the carb (steam) and Seafoam (hotsoak).
What has been your experience with either or both? If you used Seafoam, how long did you let it hotsoak? Do you need to do this more than once? Does it really work, or do I need to remove the heads? Thank you. |

Re: Decarbonize engine
spray of water down the carb throat of a warm, running engine has always worked for me-run the engine about 1500 rpms

Re: Decarbonize engine
If you have ever pulled the head on an engine that is leaking coolant into one or more cylinders(and still running) you will find that the coolant cleans the piston, valves and head like new.
My vote is for water mist. |

Woodieman is correct. That will work great.

I will work on this further today to get better/clearer pictures. It is not real good too close up. |

Re: Decarbonize engine
Back in the olden days we would slowly pour kerosene into the carb while jazzing the throttle to keep it from stalling. The pistons and chamber stayed pretty clean. I don't know whether it was the kerosene treatments or the fact that I ran the p__s out of that engine.

Re: Decarbonize engine
Every time I come back from Denver, I have to climb over 3,000 ft in 13 miles. The gas pedal spends most of its time pretty close to the floor. The drive in itself is probably self cleaning.

I was taught this method in auto shop class and a spray was used during fast idle on a slightly warm engine until there was stalling. instructed to leave overnight and then make sure nothing or no-one was standing behind the car when it was restarted the next day! The instructor was an old time mechanic with old time ideas, but they worked. |

Re: Decarbonize engine
In the fifties, my old man always bought Olds 88's with the top engine. On highway trips, he would occasionally accelerate to almost 100 (he sometimes made it if the straightaway was long enough). He said he was "blowing the carbon out". I don't really think that it was all about that.

Re: Decarbonize engine
Hey J. Franklin Spray or mist is the key. The temp will take care of itself. Just don't overwater. Hydraulic lock is a very painful experience

Re: Decarbonize engine
Tubman, my dad had Packards till 1958 when he bought a Lincoln same story. His last Packard was a 56 Carribian & i don't think it ever had time to "carbon up". Those 2 4's were open a lot..........a real car!

Re: Decarbonize engine
My dad always used diesel fuel. He would slowly pour it down the carb at a about 1500 rpm. When the motor would start to lug down he would back off until it would pick up again, then increase the amount of diesel till it started lugging again & repeat. It would smoke up the neighbor hood & stink like hell. One time someone called the fire dept cause they thought a house was on fire. Two engines showed up lights & sirens wailing!

Of course. This is another fun part. Technically known as rolling coal to the diesel fuel cognoscenti. 8^) Jack E/NJ |
