Any of you fellow oldsters out there remember the story about the 100 MPG carburetor that The Man would not let us use because it would reduce petroleum consumption too much? I seem to remember hearing that over 30 years ago, and the story was that Big Oil bought the patent and kept it secret. That patent should be expired by now, and in the US patents are not renewable, so where the heck is the old patent? I'm restoring a classic car and having one of these would fit right in with the period. In sticking with the spirit of the old story, I suppose installing one upside down would bring 100 HP, but will installing them upside down in series have a multiplier effect?
