If it has a carburetor: It'll be on top of the engine, typically near the air cleaner housing. It's a fairly large, somewhat rectangular-shaped component with various intake and outlet pipes connected to it.
To find out for sure:
1. Check your engine: Look under the hood. If you see a large metal box with lots of hoses and linkages on top of the engine, that might be it.
2. Check your owner's manual: The manual will specify the engine type and generally show a diagram of the engine bay, which will pinpoint the carburetor (if equipped).
3. Look up your VIN: Use your Vehicle Identification Number (VIN) to determine the exact engine type online through sites like parts websites (like AutoZone or Napa Auto Parts) or dedicated vehicle database sites. Knowing the engine type will help you find diagrams or information about the engine's location, including the carburetor if it has one.
Keep in mind safety: Always disconnect the battery's negative terminal before working near the engine.
