The Mayer carburetor has a somewhat similar automatic air valve to the Schebler Model D. The differences are in the spring dimensions and the bronze valve itself. Without the correct spring the air valve is essentially useless hence a number of Mayer carburetors are found with not only the spring missing but also the valve itself.
The spring dimensions are as follows. Phosphor bronze spring wire approx .025 Dia. 9 Turns with Inside dia of 23/64", Spring length 35/64" While I don't expect anyone will worry about being too precise one should have no trouble coming up with a spring that will function close enough for reasonable operation.
I have been told the Mayer carburetor came out with the 1914 Buick. Can anyone confirm or deny that priceless bit of information. I have never been able to track down any information on the Mayer carburetor.
I found in the residue of the Ocean City, Md. Palmer dealer a box of small parts marked "For Mayer carburetor." The were several springs as shown above and one original Mayer carburetor had the same size spring in the air valve. This give me confidence the spring dimensions are in fact as Mayer supplied them to dealers.

Dick

A few yrs back I bought a Mayer carb at a marine swap meet. had seen some reference to them in some of the boating mags but can't now remember which ones.
I noted then that one of the OEM applications was the first 4 cylinder Saxon automobiles, I believe 1913-16.
I'll look for the carb and see if it has any info on it that tells the city they were in. The same city libraries in their business directories is a good source of info on these obscure companies and usually list the first yrs of doing business or incorporation.

Richard/Richard,
Mayer carbs were manufactured in Buffalo, NY. They made at least two models. Used on Saxon & Universal C 4 cylinder engines, Kermath marine and Pontiac Tractor Company and/or Lee/Pontiac farm engines. This type of carb shown in photo. Cross section drawing is a Mayer of a type I've not seen. Drawing off a British site.Cross section DrawingMayer Carb from Lee/Pontiac farm engine

Very interesting. The Drawing is not the classic marine carburetor shown on the right. I would love to see a drawing of the one on the right with the detail of the drawing on the left.
There seems to be a missing word or two after British?

The one in the photo is exactly like the one I have on the Kermath 8-10 I just bought. Can you give any information or advice on it? Do they come stock with the homemade drip pan hanging on a wire under them? Ha Ha...

Several I have picked up over the years have heavy air valve springs. Apparently the original got lost and what happens is the air valve wont open with the heavy spring flooding the engine when opening the throttle.
I thought I posted a number of detailed photos on the page but cannot seem to find it today.
