elbow grease, a wire brush mounted in a drill, a good pointed awl, possibly a needle scaler and a small hammer.

you can get the engine to operating temp and use blaster tune up spray,its not too easy to find or i have used a fine mist or drizzle of water.dont dump it in or you could damage the motor.the cold water hits the hot carbon and cracks it off.i read this in an old hot rod tip.i have used the water a few times and it helped me.

A real old trick for removing carbon build up was to use a few grains of uncooked rice... Just drop a few grains at a time in while holding the throttle open and reving the engine... It wont affect the valves or pistons and cleans the heck out the combustion chamber too...


Nice twist also to the term "rice burner"

Fill up a spray bottle with water,hold the rpms up a little,and give it a few good blasts of water spray.It should cough and spit out some black sooty looking stuff out the exhuast.
I dunno about the Rice thing though what if your engine has a food allergy and ya didn't know??

Yes just and old mechanics trick that they used just prior to a tear down but also it wont hurt anything... Just dont drop a whole bag in at once... Might not be a good idea for an engine with fuel injectors...? But for a carbed engine it works very good...

Get you some SeaFoam de-carbonizer from Napa. Water works pretty good also, except I pour it slowly from a pop bottle.

Never heard of the rice deal but i have used the water trick and it works.I like atf fluid better than water, but it fouls the plugs.Just dont pour too much water or atf in at one time or you could hydrolock it.I usually use a soda bottle with a piece of vacuum line in it hooked to the ported side of the carb.It has always worked for me.I have never used Seafoam but i heard it was great.You can also use MMO, but it'll foul your plugs like atf fluid if you are not careful.......Jay

de- carbonize the combustion chamber

What is the engine doing that makes you think you need to de- carbonize the combustion chamber? Is this a common problem and if so what causes it ?

running the engine rich, or stop and go, slow low rpm driving can cause the carbon.the carbon can cause run on or dieseling and spark knock detonation from the carbon glowing red hot in the chamber .it can spark off your fuel at the wrong time like another spark plug.

Is this what they call 'pinging'?
