I LOVE old Classic cars. Specially if we could put a Pough Carburetor in it which got 204 miles per gallon of fuel - - in the 1960s. Yes, Charles Pough created a Carburetor / Vaporizer that Ford Motor Company and Breen Motor Company in Canada tested and got 200 - 204 miles per gallon. So why do we not have 200 + mpg now. Google it - check it out.
