In history-making flights Lindbergh, Byrd, Goobol and a host of other have estat. lshod dramatically and con. clusively the superiosits and reliability of twin ignition, high compression, vulré-in- head motor performance.
And all three princip es aro combined in the great now Nash Twin Ignition Motor which powers every Nash 400 Special and Advanced Bix model.

The result is inoro power from less gasoline, and ordinary pusoline at that. No spacial. high priced fuels aro required for tho Twin Igot- tion Motor.

They are willing to add, however, that if mass production can be applied to the single-sleeve valve-and so far there seems to be no doubt about this-the automobile engine will be so simplified in construc- tion and repair that the automobile buyer and owner is sure to share
in its benefits,
