Since it was clean I would suggest either bad needle and seat or float is out of adjustment. That would be my next move.

I took the float off and inspected the needle and seat it appears to be fine I put it back together and flipped it upside down and blew thru the fuel line upside down to see if it was seated the float didn't move so tomorrow I am going to fill it with fuel and blow threw it again and see I am just lost due to the fact their was no gunk or anything

Hi Khackett! Just wondering how you determined that the needle and seat where fine, It would only take something the size of a hair to let fuel under pressure leak, I would have just replaced it and eliminated it as a cause. Only two probable causes, Incorrect float adjustment or leaking needle or seat
