FORD Model T -Holley Vapor Carb
« on: September 23, 2010, 05:21:57 AM »
The last few years of the Ford Model T (26-27)could have Holley Vapor carbs  as alternatives , all the early cars had up draft carbs so the fuel had to be lifted and had a better chance of breaking down by vacuum as opposed to later cars that had down draft carbs on top ,where the fuel is poured into the motor like a drain pipe.
Fordson tractors also had vapor carbs ,when times were tough pretty much any fuel could be used
in them as long as it would evaporate, alcohol and vege oil ,old engine oil.
Holley doesnt acknowledge their old fuel saving devices.
Ive got one of these old carbs but its burnt out ,they turn up on ebay still though.

They're doing some interesting things now with Ultrasonic fuel vaporization.

What you can use is a carb from a forklift that uses propane.  Have a tank is heated between 170 and 190 degrees or so to vaporize the alcohol in it.  Have a fuel line at the top that runs to the carb.  You may have to change the jetting somewhat.

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.
