Just a quick FYI I found while trying to de-carbon these 2.7 pistons and valves. Permatex Gasket Remover takes off carbon quickly! 20 minutes, and a stiff brush. A Soak in hot water with Simple-Green solution [few ounces per gallon] for a day or two does the rest! I used nothing more than a toothbush. I'll have some before-and-after pics this weekend when I can find my camera. I like lo-buck, and no abrasive cleaning. The Simple-Green also seems to leave a residue that resists rust. So dont rinse and polish the part unit you are ready to use it.

 

In the car put some cardboard under the exhaust exits...find your favorite bottled water and pour some in the carb. You will get some real black carbon out of the back.

 

Brake cleaner has always worked for me..


And in car I usually like drawing in ATF through a vac line. And a cup or so of ATF in the gas tank also does wonder!

 

OK, I upped the game today! I now have a Ghetto Hot-Tank! I bought an 18 quart roaster from Goodwill today for $5. Couple gallons of water, and about 12 oz of Simple Green. This thing is the ****! I let it simmer all day and my parts are spotless and non-toxic. Non-flammable is a plus too.
