How many kids today know about timing advance, ignition points, and what a timing light is? I am old.
In my youth I could tear an engine apart and work on it. With all the electronics on a modern engine today I can not. However, these new engines are masterpieces of engineering relative to efficiency, power, and low emissions.
You can do it.
Watch YouTube videos about the car and engine.
Start and maintain a part number text file for everything, including supplies that you will use.
Get the manuals - digital esp.
Get a diagnostic computer of some type, and learn the codes - spend a lot of time on this.
IOW, study. That may take several months. Aiming to become very familiar with the car and engine, and how the engine works - how the electronics and other systems work.
How about “dwell” and vacuum advance vs centrifugal advance? And always replace the condenser when you replace the points?
