The picture above with a RED CIRCLE shows where to locate the carburetor number. During checkout, there will be a section to enter your carburetor (core) number and vehicle information when ordering this remanufactured carburetor. Our staff will use this information to ensure you receive the right carburetor. If we have any concerns, we will call and or email you before shipping the carburetor.
