Agreed. I have never tried it "wet" either. (running) Idle it down real slow. I don't like cleaning the engine and inner fenders off. LOL

Exactly. I don't know "what's got into" the cats that insist that adjusting running and hot is the only way. They're crazy. I don't give a DAMN what "the book" says. lol
