Don't be sorry. If you're new to the car thing gotta learn somehow. It's basics. Plugs, maybe wires. Check timing. Carb is tuned for best vacuum or ideally you have it hooked up with an 02 sensor and make sure its pulling good numbers through the driving range. So maybe some jetting/carb changes. If it needs them. Check ignition/spark quality. Etc etc. Just the real basics of how the car runs. A proper tune on a poorly/bad tuned car can be with 10+ horsepower alone. Or more.
