What are some of the counter intuitive things (and their fixes) you have learned about a Model A? For me, here are some of the things that I didnt expect and cost me time figuring them out. Im still fairly new to Model As. Please correct me if I get any of the following wrong.
2) The metal linkage rods that connect the steering column spark lever (on the left side of the steering wheel) and throttle lever (on the right side of the steering wheel) to the distributor and carburetor have ends on them that fit over linkage balls. The linkage rod ends are spring loaded and stretch so that you can remove the rods from the balls. Up to you, may want to mention how the GAV/Choke Rod disconnects from the carb, also unique.
5) The Model A does not have a VIN (Vehicle Identification Number), in terms of what we call a VIN on modern cars. (VINs were federally mandated in 1954, and the newest Model A is a 1931.) Instead, it has an engine number stamped on the driver side of the block. That engine number should be on your car title. That engine number should also match the stamping on the frame, which cannot be seen without at least partially removing the body. (Ive never seen a stamped body number, but I am told it is on the driver side of the frame, under the cab of the body.) As a side note, I think motors were stamped on the line when installing the motor on the frame, to match the frame #. So the correct # is what is on the frame.
6) If the car has been sitting for years, its a good idea to drop the oil pan to clean out the sludge, including the oil pump screen, that is likely to be present. Also recommended is cleaning out the valve galley located behind the valve cover, and additionally cleaning the 3 small oil passages located in the rear bottom of the oil galley. However, the oil pump can fall out as your remove the pan. Model A parts dealers sell a device that screws into the side of the engine to prevent the oil pump from falling out. If you decide to use your own screw, be aware that the thread is not a standard thread that is likely to be found in your toolbox. The hole is easily stripped with an improper screw.
Starting the Engine
A. Release the lock cylinder by turning the switch key to the right as described on Page 6. - Please note a lot of cars do not have the Lock Cylinder ignition switch, I believe the locking style is only on certain year, earlier As.
C. If the engine is cold, turn the carburetor adjusting rod one full turn to the left starting from full CW, to give it a richer mixture for starting.
10) It is recommended to use the Barn Search function as the vast majority of questions/subjects have been previously discussed. Forum members appreciate those who have done some homework before posting.
Note - Have reworded the above to be positive and guide Newbies to the forum.
13) Unleaded ethanol gasoline will burn okay in a Model A. Leaded has was not available when the car was manufactured. However, the alcohol in ethanol tends to collect moisture, which will cause the gas tank to rust. If that rust breaks free from the tank, it tends to clog carburetor parts and possibly score the gas shutoff valve.
