Known-Good Waveform
This vehicle does not have fuel injectors. It uses a carburetor (typically Carter AVS or Holley 4-barrel) with mechanical fuel pump driven by the camshaft. Fuel delivery is controlled mechanically through jets, metering rods, accelerator pump, and power valve based on intake vacuum and throttle position.
