Lots of Carter YFs interchange with lots of different makes and models.

My truck had a cobbled together Carter carb with parts from an early 50s Jeep and a mid 60s Jeep. Of course the metering rod was not ideal for the 216 Chevrolet.

Talk to Carbking and locate the CORRECT Carter YF for your specific application and then rebuild it. I did that and the Carburetor has functioned flawlessly for 4 years and over 10,000 miles.

The Carter YFs all look about the same but they are not the same. Here is my correct carb next to the incorrect one. You can see the slight difference in the casting just behind the fuel inlet in the first two pics.
