The basic purpose of a carburetor is to:

  1. cool the engine

  2. ignite the fuel

  3. measure oil levels

  4. regulate the mixture of air and fuel

The correct answer is: regulate the mixture of air and fuel

A carburetor is a device that mixes air and fuel in the correct proportion for combustion in an engine. Option A is incorrect because cooling the engine is not the primary purpose of a carburetor. Option B is incorrect because igniting the fuel is the job of the spark plug. Option C is incorrect because measuring oil levels is not related to the function of a carburetor. Therefore, the correct answer is D, as it accurately describes the main purpose of a carburetor.
