If you're experiencing starting problems that *might* seem related to a choke issue (like stalling after starting, rough idle when cold), the problem likely isn't a manually adjustable choke needing adjustment, but rather one of the following:
* Faulty Automatic Choke: The choke mechanism itself may be malfunctioning. This often requires professional diagnosis and likely replacement of the entire carburetor or parts within it.
* Carb Issues: A dirty or malfunctioning carburetor is a more likely culprit. This might include clogged jets, worn-out components, or a vacuum leak.
* Other Starting Problems: A weak battery, faulty ignition system (distributor cap, rotor, wires, ignition coil), or fuel delivery issues (fuel pump, fuel filter) can also mimic choke problems.
Instead of trying to adjust a non-existent manual choke, you should:
1. Check the basics: Ensure the battery is fully charged and the fuel tank has fuel.
2. Have the vehicle inspected: Take your Fifth Avenue to a qualified mechanic specializing in older vehicles or a carburetor specialist. They can properly diagnose the issue and make the necessary repairs.
Trying to "adjust" something that isn't there could damage the carburetor and lead to more expensive repairs. Professional help is the best approach for diagnosing starting and idling problems on a vehicle of this age and technology.
