Here's their claimed benefit:

It's designed to replace the idling adjusting screw for the purpose of
pre-heating the fuel and air mixture.
Normally, as the air and fuel mixture pass through the carburetor, they
create a refrigerating action which obstructs the idling orifice and the
engine stalls. The Jet Heater de-ices this orifice which results in smooth
idling performance. Also, the fuel is more readily vaporized and the ful
mixture is more stable.
The total effect is a smooth idling engine where choking is at a minimum
necessary only for starting. Due to less choking and improved vaporization,
fuel consumption is kept to a minimum.
Faster starting - Better mileage - Smoother running !

I kinda like Calvin's George Carlin quote.

Best, Joe.
