How do you guys remove carbon from the combustion chamber. I have the heads off. TIA.
From the head, wire wheel. Purple degreaser works well once the heavy stuff is off and rinses off with water.
Oven cleaner works too, but don't let it linger on aluminum. The cheap oven cleaner etches worse. I use Easy Off.
Caution: It dissolves carbon; YOU are a carbon-based life form.
