Just a bump of an old thread. As I was telling perely in his 1929 Essex Highboy thread, I haven't done much to my 52 since I pulled it out of storage. It was running real ruff on my last ride and decided it is time to start taking it apart and updating a few things. For my birthday, I received a little cheap Habor Freight parts washer. So I knew it wasn't going to handle extreme cleaners. But would Purple Power or Slimey Green be strong enough for the engine tear down.
