RE: Need a way to clean dirty engine
Hi Tucker,
Another way not mentioned so far is to use a chemical called Methylene Chloride, which is the primary ingedient in most good paint strippers. It is sometimes a bit difficult to find, but it works wonders. It is kind of "goopy", brush it on, wrap parts in foil or saran wrap and leave overnite, then wash off with hot water and a brush.
