Ammonia is used in many new clock cleaners and it actually eats away at the metal, and the last thing you want in a clock cleaner is to have it eat away at crucial parts like bearing and teeth. But I am not sure this cleaning solution or Ultrasonic cleaning would dissolve the hardened gunk in a carb or furl pump. Ulsonic cleaning basically clean dirt that IS stuck to the moving parts it does not really dissolve deposits. I think the Naphtha or lacquer thinner does that kind of dissolving

I think the guy said he used a Dawn dish soap and water solution. Again, I just saw this somewhere and thought I'd chime in. I do know my wife has a cheapo ultrasonic jewelry cleaner that she says works much better than anything else she has ever used.
