My understanding is that you check float levels at idle. I have heard that you can use "a cut off bottom of a soda can" or "a rag" to catch the fuel spillage.

Based on what I have recently learned... your problem may be accelerator pump related, and my guess is that is where you are going to find your fix. However, wtm442 will give you an expert opinion, I just offer this for your consideration until you get an answer from him or someone like him.
