Thanks very much. I was going to spray some Seafoam into the brake booster, Just a little when it's running. I have the carb cleaner and I lost the stick. Lol So spraying down at the threads would help if I had that. It's been cold so I'll have to put off something that bugs the Hell out of me.
Brown, Black,and red. Are you talking about the color of the metal. Brown/Red meaning the color of the metal heated up after high temps? Black meaning a leak? Again, Thanks for your input.
