  • Air Cleaner

    So lets say we have done the balance mod on the carb and we want to use a air cleaner. What is a good one to use? What about the issues with possible raw fuel fires?

      Look for the balancing system on a Zenith, that uses a copper tube from the float chamber vent, to the side of the air horn, just in front of the choke butterfly.

      Thanks for the information. I'll be ordering the 5.5 inch K&M. But I'm sure the flat earth people would claim that since Henry designed the A without a filter we should not use one. Same as they claim we should use single weight non-detergent oil!

        We've had good success with the 5.5" K&N washable type as per the article, with a Marvel Carb. Clears the engine pan and air flow appears to be as good compared to no filter. The small paper one appeared to restrict the air flow in our application when tuning the carb.

          My brother was looking somewhere and found the K&N filters let through the same size particles as the old ones I forget the names. They both let though the particles that do the most damage cause they get around the engine easy. So in the end you are best not bothering.

            I'm using the K&N "High Boy", and the Marvel carburetor. I live on a dirt lane 1/2 mile long, and wanted some protection.

            It it seems to run perfect and idles nice and low.

                I run the airmaze with the paper air filters on all my Model A's. They run perfect. Lots of power (look up 'Model A vs. Stearman biplane' on YouTube!) and they idle very low, and very smooth. Also, using this combination made the cars very quiet. The fordor idles so quiet that you can barely tell it's running.

                The paper filters also filter out enough dirt that the engines do not suffer any wear from dirt in the intake.

                Yes, I have heard and read all the negative comments about the airmaze and the paper filters. However, as an engineer, I did my own experiments first, and concluded that the air flow or pressure are not affected enough to change the mixture, rob power, or cause any differences in running parameters. A Model A motor at 2,500 RPM does not draw enough air to make the paper filters restrict the flow. They work great.

                  I think the biggest draw back on paper is it will absorb any fuel that finds it way out of the airhorn. Many of the ones i had removed had removed have some yellow staining

                Finally got to work on the roadster today, first day since buying it. I already have the short paper filter in my maze. I need to look at the carb to see if its modified.

                  What I've seen for a B carb looks to have way too much pipe hose on it. Anybody know of a good source for B carbs? They take one a little bigger than an A Zenith.

                    If you clean your butt properly, that is not an issue.

                    FYI, dry paper wiping is not enough. If you got poop on your arm, and wiped it with toilet paper, is your arm now clean? Of course not! Clean your butt after every BM and your butt will be as clean as the rest of your skin, thus no marks or odors on seats.

                    I have the balance mod done. Tried and lost a hi boy (too much to try again) found and have been using a filter from ebay. Cone shape, oiled like K&N, with 45 degree neck. $15 works great. Search 45-48 mm input filter. Zenith input 46mm, if I recall correctly.

                    No, I have not tested the flow, but have gotten to 67 and cruised at a steady 60, so it meets my needs.

                      Some thoughts; the '31 Lincoln came with an air cleaner and so did other makes. Air Maze was offered by dealers, especially in the dust bowl years and to help keep out nesting bugs. Probably came down to cost and Ford's resistance to changes ?
                      BTW, our old Air Maze collar fits the K&N ,with a longer thru bolt, and the Marvel carb throat.

                        Question? "So lets say we have done the balance mod on the carb and we want to use a air cleaner. What is a good one to use? What about the issues with possible raw fuel fires?

                        Outlandish Scientific Model A responses very rarely heard:

                        A. Scientific Model A Carburetor Filter/Balance Test:

                        1. First, try placing triple paper bags over you head with an elastic band sealing the paper bags around your neck and try to run a mile ....... carburetor venting and balancing is required in a similar case because of lack of air flow ........ solution, punch vent holes in the paper bag to obtain air from the atmosphere.

                        2. Second, similarly, place a different material like breathable K & N carburetor filter material around your head and try to run a mile ..... similarly,, carburetor venting and balancing is not required because of ample airflow ...... no vent holes needed in carburetor to obtain more air from the atmosphere simply because the air filter surface is large enough so as not to constrict the amount of air flow entering the carburetor.

                        3. If air ample Model A carburetor inlet air flow vs. Model A carburetor atmospheric venting is still not understood, maybe try running a mile with two (2) ear plugs in your nostrils and with your mouth fully over-stuffed with ripe bananas.

                        B. Scientific Model A Carburetor Filter Position Decision:

                        1. Lets say someone has a very normal, "slightly" leaking Model A fuel shutoff tank valve that leaks very seldom; and a normal, "slightly" leaking Model A carburetor that leaks very seldom; and one has to make a choice as to where one should place a Model A air filter that may or may not get soaked with raw wet fuel ................ and may or may not become ignited just in case this Model A engine backfires.

                        2. Next, try observing several air filters on later model cars, and try to guess why air filters were not positioned by automotive engineers under a possible "slightly" leaking carburetor that might get fuel soaked when it is choked or not choked, and might get ignited "if" this engine backfires.

                        3. If a Model A engine is vibrating too much, and/or if traveling on bumpy roads, to where erratic motions causes a Hi-Boy K&N filter to fall down, never a bad idea to follow former suggestions on how to securely fasten a Hi-Boy so it stays in the vertical position.

                        C. Life Safety:

                        Never a bad idea to first read the insurance policies on garage, house, and Model A ...... worst part is time loss to replace same .............. as far as Life Safety, their is no replacement for life, and somebody else will enjoy buying treats with your life insurance benefits.

                        Hope this helps.

                          by Ayyy
                          After many priority shifts and procrastinations, I finally got around to installing the vintage centrifugal air cleaner on my 1930 Model A CCPU.

                          What's a vintage centrifugal air cleaner?? This air cleaner was patented in 1922 and it works by centrifugally throwing the particles out of the air stream heading towards the carburetor. It does not use a mesh filter, so there is no restriction...

                          ALL of the carburetors released by Ford for use on a Model A or B
                          had the float bowls EXTERNALLY vented.
                          So the use of an air cleaner of any type will negatively affect the air to fuel ratios.
                          These carbs were not designed for air cleaner use.
                          To allow the use of an air cleaner the bowl vent must be relocated to the INSIDE
                          of the carburetor near the choke plate area.

                          I was wondering about maintenance of the Air Maze filter setup. It's like the grandfather of the K&N filter and I got to thinking, could the wire screens be sprayed with a WD or K&N's lube or even just dipped in some oil, if that would actually make a big difference vs without the oil treatment.

                          Are you doing this?

                          I just sprayed one with WD...

                          Air Balancing a Zenith Carburetor for us with an Aftermarket Air Filter ??
                          by conaway2
                          I’ve read a number of opinions on this, and, after just installing a highboy K&N air filter, am wondering if I need to worry about this. From what I’ve read, all that is required to air-balance a Zenith carb is to drill one hole...this sounds pretty simple - does anyone know if this is correct, and, if so, where the hold should be drilled ??

                          thanks - Jim

                          by Poor Boy
                          Good morning guys. I came across this device attached to a Model B carburetor. At first I thought it was an air cleaner until I looked closer. It must be some kind of silencer or velocity stack. The inlet is shaped like a Venturi and looks like it might speed up the inlet air. Any experience with something like this or even a good guess. Thanks. Jim. ...

                          Air Maze air filter on Zenith Carb
                          by conaway2
                          I’ve used the Air Maze filter for almost 30 years - recently replaced the ‘screen’ filter element for a real paper air filter. The rebuilt engine was installed in March, carb rebuilt a couple of months ago - engine runs very well. I can turn the GAV off and the engine begins to stumble, so I believe at 1/4 turn of the GAV out, the engine is getting a pretty reasonable mix of gas/air.
