Hello, and thank you for choosing Just Answer. My name is***** will be happy to assist you.
The reason your air box filled with fuel, is very likely due to your carburetor flooding.
If your float is sticking, or leaking, or if your needle is not properly sealing in your carburetor seat, this can cause your carburetor to flood.
If you remove your fuel bowl from your carburetor, you will have access to your float, needle, and seat. Check your needle and seat for wear. Also, check for sediments in your fuel bowl, that could have lodged between your needle and seat, preventing your needle from stopping your fuel flow, as your float rises up.
You are very welcome!
