Cannot help on timing, our database is primarily concerned with carburetors. Jon.

Wanted - Oakland literature, and unusual older Pontiac literature such as Pontiac Owners Magazine, Pontiac Warrior Magazine, GM Folks Magazine, factory service letters, factory sales letters, inspector's guides, filmstrips, training movies etc. Thanks. Jon.

Current production carburetors will have linkage and fuel line issues. Also, the original air cleaner will NOT fit current production carburetors. Best bet is to rebuild your original carburetor, then you KNOW it is the correct one for the car, not a "generic" replacement. Parts are readily available for you to rebuild your own. Jon.

Have no information for the 1910. Database is good, but still incomplete. Always welcome input with factory documentation. Jon.

Exact identification of the Stromberg glass bowl carburetors is difficult to impossible; as there are no identifying numbers on the units (other than style and size eg. A-3 which would be a style A size 3), and each physical style and size could have up to 5 different venturi, different throttle arms, jets, etc. It is, however, quite easy to identify each unit into a group of application by style and size. Jon.

Schebler model L carburetors were problematic when new. For driving purposes, most replace these units. If you wish to stay with the brass look, Stromberg series M and O carbs are much superior. If you are not concerned about the brass look; Stromberg SF and Zenith 63AW series are better yet, and less expensive. Jon.

The Stromberg O series carburetors used a main venturi (the large one) and a booster venturi (the small one). Normally, these break when removed, and new ones must be machined. Occasionally one gets lucky with the removal. The main venturi is held in place by a set screw. Often the main venturi may be removed by removing the set screw, then placing the carburetor body in a zip-lock bay, and then placing it in your freezer overnight. A little penatrating oil placed on the throttle bore AFTER removal from the freezer helps. The booster venturi is held in place by two points: (1) a brass screw coming into the booster from outside of the carburetor; and (2) a locating pin which is a part of the booster which is inserted into the carburetor body. The location pin allows the booster to be held in the vertical position with only the one screw. We have NEVER successfully removed a booster venturi (even from new old stock carburetors) without breaking the locating pin. Jon.

Our database indicates the Schebler Model L was used as original equipment on the 1911 Model 30. Have found that often the model is more definative than the year on listings in this era. Jon.

The Schebler Model L carburetor was troublesome when new, and unlike a fine wine, not improved by age. Finding a suitable replacement requires several items of data, some of which you have already supplied. The flange size center-to-center of 2 and 11/16 inches is referred to as an S.A.E. (Society of Automotive Engineers) size 2 flange. Most updraft carburetors were of the straight flange configuration; however you have indicated the need for a cross-flange carburetor. Stromberg is probably the best source for cross-flange carburetors, and they will be identified with the letter "X" in the carburetor type - eg a Stromberg model O-2 is a straight flange size two carburetor, whereas a Stromberg model OX-2 is a cross flange size 2 carburetor. Zenith also made a few cross flange units as did Schebler in their later model S (also problematic). Carter did not offer a cross flange updraft carburetor in S.A.E. size 2. Another option (assuming you have the room) would be a cross flange adapter. This can be easily machined from a piece of aluminum flat stock of thickness 3/4 inch to 1 inch, and simply looks like two carburetor flanges welded together at a 90 degree angle. The use of an adapter opens up additional manufacturers of carburetors to use. The other item of data needed is engine size. The size 2 is a physical size only. Within each physical size carburetor, there may be as many as 10 different internal venturi sizes; and the venturi area is what determines airflow. It is important to size the carburetor airflow capacity to the airflow requirement of the engine. However, before "throwing rocks" at the carburetor, as others have mentioned, checking the ignition system and general engine condition is a good idea. The best carburetor in the world will not solve a faulty ignition system. Jon.
