  On my 35 I have the original carb air cleaner that you put oil in the bottom of it. Looking at it I can not determine how the oil helps. It's not like the air being suck into the carb goes through the oil. What is purpose of the oil.

  the air actually goes over the oil and in doing so the dut particles adhere to the oil surface,also in the top half of the oil bath cleaner there is a steel mesh that gets a film of oil and dust sticks to this also thus helping to clean the air--not anywhere as good as a paper element but a way lot better than the old dry type

  Henry Ford had a strong bias against filters of any kind. The carb on the Model A was designed to face the throat backwards, as he thought that the inertia of the road dust, etc, on the primitive roads of the time would flow back past the intake as the vehicle went forward, and not be inhaled. The oil bath cleaners depend on the same inertia to cause the incoming air to be thrown against the oil pool and trapped. The same theory is used in the "cyclone" air filters on large diesel trucks, but without the oil, in most cases. The dry (paper) filter technology today is extremely effective, and used universally. We have adapted our oil bath cleaners to use modern elements, and I'm surprised there hasn't been a kit marketed to do the same.
