Default Air cleaner

I have a Touring engine plus a tillotson Model X carburetor. Would an air maze air cleaner have enough capacity for this engine. Since the carburetor is and air balanced carburetor running and air cleaner should not be a problem. Any advice would be appreciated. Gerald

I have a Air Maze filter but I used this K&N filter. Fits the Air Maze but much bigger element. https://www.amazon.com/9257-High-Per...s%2C194&sr=8-1

The expanded metal mesh air filter should not be a problem on that engine.

How did you air balance this carb? Can I see some pix? That's cool.

The breathing of a Model A engine is restricted by the size of the stock carburetor and stock intake manifold. Adding that air filter will not change the performance. Adding an air filter to a carburetor that is not air balanced can cause the engine to run rich, depending on the restriction of the filter.

Any filter you put on the intake side of the carburetor reduces the volumetric efficiency of the engine. So called balancing the air pressure inside the carburetor to "make work" an air filter does zero to improve volumetric efficiency. The Model A's updraft fuel intake system as it came from the factory is poor, and adding a filter makes it worse. If you must have an air filter, find an oil bath one which was common on cars in the 1930s & 1940s. The oil bath is the least air flow restrictive, but they are large, bulky and ugly.

Pretty happy with a Highboy and low restriction K&N filter on my 31.

I would get rid of that paper filter and replace with steel mesh.

Unless all your driving is on dirt roads there's no obvious benefit to have a filter anyways. Henry did not have them at the factory.

I had one for my Zenith for 15 years and never had an issue then I decided to remove it for some pictures and kept it off. No issues without one for the last 12 years.

I like your set up! Nicely done!! while 'volumetric efficiency' is the keyword, overall... ie, combination of the parts - bottom line is no air filter is not road worthy! I have sold thousands of K&N filter systems, even modding up custom kits for my customers when required! stock oem vs K&N, the K&N will definitely improve overall volumetric efficiency of the (a) engine. volumetric efficiency is not a set in stone factor (#) it varies with the combination of the parts total effective efficiency.

I am a big believer in an air filter. My original AirMaze has the metal element that I clean periodically, then dip in oil and let dry. It is REALLY dirty when I wash it. If you use a paper filter I think its best to invert it so it doesn't get gas saturated and then catch fire.
