Need help with edelbrock 1406 carb

What is more of an issue today is the quality of fuel. Ethanol eats the inside of carbs if let to sit for any length of time, and ethanol destroys Viton seals causing flooding. This can happen to any carb. Ethanol also eats the plating on steel gas tanks putting rust and oxides into the fuel system, also leading to leaks.
I had this issues several years ago and was at Carlisle where Herb McCandless recommended a product called Carb Defender from a company called Driven. I have used it religiously ever since on 3 carbed LA motors and the Weber on my Rampage with no further issues with internal corrosion.
