If ya want to clean carbon from an engine follow the old farmers method..

Start and bring engine to operating tempture.

Get about a gallon of tap water


Bring block in park to approx 3000 rpm.

While you are at 3000 rpm "slowly" pour water into the carb or in our cases the throttle assembly


At no time do you want the water to stall the motor so stay in the throttle and feather the engine to over come the addition of water..

As you do this make sure the exhaust is not pointing at another auto or something you care about because the carbon is gonna shoot out of the tail pipe..in a liquid form as black water..
