I have an otherwise good Keihin PWK but I screwed it up by soaking it and trashed the special o-rings between the body and the needle stack. I hear they aren't available so I had to get a new carb. Has anyone ever found a suitable replacement for these o-rings?
are the o rings kinda brown in color? I suppose they're just like the gasoline resistant o rings that ford uses on their fuel rails. You might try a ford dealer and see if they have the right size for ya.
