Decarbonising the Head and Valves

Hi Huffer,
If you pull the valves out they are easily cleaned with a motor driven wire wheel, and various shaped and sized wire wheels chucked in a Die Grinder or even an electric drill will make quick work of the combustion chamber and valve seat area.

3 ways,
1. usual mechanical means scraping brushing and rubbing and scratching.
2. put back together as is and spray water in carbs on hot running engine.
3. Boil vigorously in water or better place above water for steam vapor only.
2 & 3 should turn carbon crust to soft grey power that rags wipes off.
Water carbon reaction used long ago to create "producer gas" from
coal React steam with coal at very high temperature- converts carbon
to carbon monoxide, and reduces some of the steam to elemental hydrogen.
Ok there is a 4th way using homeopathic 3xxx Dr. Willard water catalyst, he developed it for rail road diesel piston carbon/varnish that would just wipe off after soaking.
Maybe a 5th way using ATF and boiling or while engine running but then smokes
to hi heaven while house plant sprayer just give nasty grey mess out headers.

Most commercial engine re-builders will have a dip tank which they use for de-carbonising engine parts. A chemical process like this followed by hot tanking and final cleaning with bead or vapor blasting is the best possible method for removing carbon.

I have good luck with my soda blaster. It cleans the carbon and appears not to damage the aluminum in any way (like glass beading). I then rinse the hardware in a mixture of 10 parts warm water to one part white vinegar to get rid of all the soda, then hot soapy water. I have started to use my soda blaster to degrease parts. Much cleaner than Gunk, Carburetor Cleaner or kerosene.
My soda blaster is a cheap ($50) hand held media blaster which can be found at Harbor Freight or TIP tools. Be sure and use soda media for blasting and not the stuff at the food market (too expensive). A 50 pound bag costs about $25.00.
Good luck
