FORD Model T -Holley Vapor Carb

[Magluvin]

My great grandfather was involved in the early days of ice engines.

One pat that i remember had the pathway of the intake run over the top of the head which heated up the intake mix to further vaporize the fuel.  And, the intake valve was not driven by a cam, only the exhaust valve was cam driven, as the intake valve was just spring loaded and the intake stroke caused enough vacuum to open the intake valve during the down stroke.  I imagine these were likely low rpm engines in the beginning.
