Which solution to use to remove Carbon Particles on inner side of metal cylinder without damaging cylinder?

Question

Please suggest solution only as the Carbon Particles cannot be removed with hand .i.e., hand cannot reach inside of the cylinder.

Also REMEMBER that while cleaning that cylinder the CYLINDER itself should NOT get damaged.

The Cylinder I am referring is none other than Silencer of Scooty Pep.

Answer 1

You should not need to de-carbonize Scooty's silencer.

It is a 4 cycle engine and they do not build much carbon in exhaust sytem.

Scooty is not too old either,,they only started in mid 2003

But if you WANT to clean it,,,and if I understand you to be reffering to the SILENCER,,,The Exhaust System ( In English)

>>REMOVE it from Scooty
Spray it full of OVEN CLEANER.
In America we have a name brand called "EZ-OFF Oven Cleaner"

Let it soak a few hours then rinse it out with water.

DO NOT let any Oven Cleaner touch any ALUMINUM parts.

It will eat them/Corrode them very very badly,very quickly.
It is a VERY powerful and aggresive chemical.

ONLY use on Steel or Chrome.

If You are Not CERTAIN of the type of Metal,,Do Not Do This.

If You want to de-carbonize the inside of the actual ENGINE without taking it apart----
Read the Answer to your question from TBWrench.

He is Correct about DRIPPING or Misting water into Engine as the engine is running.

TBWrench gave You very good advice about an Old & Well-Proven Method.

Many people Know it.
But Many people Do Not.

To those who Do Not Know it,it always sounds Crazy.

It's is Cheap,Simple,Fast and it works like a Miracle.

There are 2 Cautions I would add.
#1 Do Not feed Too Much Water,Too Fast.
Do Not Accidentally Spill Too Much Water Into engine.

Water is a Liquid and Liquid Does Not Compress.
It acts like a SOLID.

If Too Much Water fills your engine while it's running,
it will act just like you dropped a BRICK into your engine.
It will BREAK something.

The Procedure is VERY,VERY SAFE if You are Careful.
Nothing works better.

# 2 Caution
When You Spray or Drip the water into the Engine,
The Carburettor Opening where you will add the water has some Small Holes or Orifices,,Passages.

Do Not let the water get into those small holes.

Restrict the water flow or mist to the Center of the carburettor's Intake Bore.

The water will cause problems if it gets into those small holes.

I prefer to introduce the water thru a vacuum line whenever possible.
But Scooty does not have a vaccuum line or port,,I do not think.

Be Careful and you will get SAFE,FAST Easy Results ,,for Free.


**For anyone who thinks that spraying water into a running Engine is a Joke,,
I remind them that Water Injections Kits were once Very Popular GIMMICKS for Horsepower,Gas Mileage Boosts in America in the '50's and 60's.

It was just a plastic bottle with a hose which connected to an engine vaccum hose.

They did not REALLY Work to increase Power or Economy as-advertised.
But it was found that they DID DO a marvelous job of Cleaning Carbon from the engine's combustion chamber.
That in itself improved many engine's running.

The things were common on the market for 20~30 Years.
If they were doing Damage,,there's No Way they would have stayed around that long.

By the Mid '60's it became Hard to sell people a plastic bottle and a few feet of small rubber hose for $20~30.

Its NOT as crazy as it may sound.

Answer 2

If the cylinder is off the engine, you can use Acetone to soften and remove carbon.

The thing is, if there is carbon actually stuck to the cylinder walls, then the bore is compromised, and you need to get larger pistons & have the cylinders bored.

If it's just a carbon ring above where the piston sits at TDC, then just saturate a paper towel with acetone, and lay it on the carbon, let it sit for 5-10 minutes, then the carbon should just wipe away.

You can use it on the combustion domes in the head also. Just don't get it on any painted surfaces or rubber seals.

Answer 3

hi, if the engine runs this will work. it may sound way out there but here goes. i learned this trick while attending AMI-american motorcycle institute, in daytona fla. in 1987 and have used it often.
first get the engine running at normal temp. then spray ice water from a spray bottle into the carb opening. you will have to keep the engine running while doing this so two people are best. one works the throttle and the other squirts. dont over do the rpms or go too nuts on the water spray. you will probably see alot of black stuff coming out the exhaust, thats the carbon.

this trick is used alot on early evolution harley engines that would have pinging problems due to carbon build up on the piston tops.

i would have never believed it if i hadnt seen it done, and probably never would have tried it either, but i swear they taught it to us and i have used it many times in my 20 years as a h.d. tech.

best wishes. tbwrench
