@Shawns Fords: Which extractor tool from Cornwell are you referring to? I looked on their site and they have quite a few. I would love to know which one you use (anything to make a potential bad job easier).

Regarding SeaFoam, I love that stuff. I've used it for years and it works wonders. I've used it in oil to clean the system, ran it through gummed up carbs to clean them, and put in my bike every winter as fuel stabilizer. That stuff is awesome. Reminds me, I need to get some more, used the last bit in a push mower that hasn't been started in 8 years (worked great).
