if you are wanting to clean carbon out of the cylinders, just slowly pour some ATF into the trottle body and keep the engine rev'ed up so it doesn't stall. it will puff a lot of white smoke, but that's ok. the atf will leave the cylinders spotless inside. if you are just trying to clean the valves, intake, and tb... just spray carb. cleaner in there while the engine is running and keep it rev'ed up.
