Fox carbs are less than perfect for sure. I experienced the exact same symptoms with a Fox 60 Eagle IV. I have found a web site that is dedicated to Fox engine carburetor problems.They describe how to fix them with a slight modification. However, you can order an adapter from PERRY Carburetors and use the appropriate Perry carburetor for your engine and the problem will probably go away. I am in the process of doing just that now . I Purchased the adapter (14.95) and waiting to receive it. You can check on the Perry carb website for carburetor for your Fox. You will have to call them for the adapter.
