Isn't it funny how your buying experiance of China Girl engine kits will lead you into a direction. My experience always leads me to THAT'S DAX to buy parts but not there engine. I think I have made a big mistake. If I want to add a slant angle plug head to my engine there is web sites that sell them. If I want to add new style carburetor, there is web sites that sells them. If I want to add different style exhaust their is web sites that sells them. ..etc. My engines will be through That's Dax from now on. Forgive me Dax for being a newbie fool.
