Ditched the "Air Maze"...

[2speed]

I have many farm tractors that have a gravity fed fuel system, and they all have air cleaners on them, and yes they do leak sometimes. But the air cleaners are higher than the carb, with a pipe and flexible hose connecting them, so they don't fill with gasoline.


They almost all have Marvel Schebler carburetors on them, I have not looked closely at the Marvels to see if they have the pressure balanced system on them, or they may not work the same as the Model A carb.


Is the Marvel Schebler carb for the Model A pressure balanced?


I would be interested in the pressure balancing to run an air filter. While everyone may so and think that there's minimal dirt, I spent a lot of money on my engine, and I put a lot of miles on it, so I would like it to last.

i work on a 15-30 mccormack deering which uses its own brand (stock) of carb. it has an air cleaner and for sure it has an air balance tube from the intake pipe to the carb. it is original.
i also work on a 20-35 allis chalmers with an air cleaner, and a carb that looks like a marvel (im guessing the carb is not original), i don't see a separate tube on it.
