Thinking about it, I guess I'll concede that the thing will run as he has it built.
His video shows that much..
Interesting;
Some early carburetors were simply a sponge or wick that pulled wet gas into the material. (like a wick on a kerosene lantern)
On those early carbs, Air passing into the motor/over the wet sponge drew air/gas mixture into the motor..
Was pretty crude, but it did work in early automotive history...
On his invention, the 3 hoses would limit the amount of air that he can pull into the engine.
I assume he wouldn't have enough volume for higher rpm's. (so his RPM range must be limited)...
And as stated by others,,, the AF ratio, would have to be perfect to work at all...
Thinking out loud; Something like this could work on an engine that runs a constant RPM.
Like a old industrial water pump etc... But would be a PITA for other uses...
Ride safe, Ted
