Ott3r, your question is a bit hazy, any warping is a no go on a model "B" it is beyond repair. Normally it's the air horn (the top piece), if it is warped there is no way to make it better. I have purchased many nos stock model B parts from a good natured fellow on Ebay (12bolt_tom). His prices are reasonable and service is fast. Also, it would be extremely rare to have a warped float bowl. The cause of your problem is from over tight screws on the air horn (4 large screws). If you need any more help or have difficulty I'm always here. Doc.
