I think maybe the float level is set too High.

I've attached a clean hose to the carb inlet with the bowel off and while blowing into with my mouth gently raise the float with my finger to see if it stop letting air in and at the correct level.

Got back to the carb tonight. Spent 2 hours on it and nothing. Set the float too high, set too low and everywhere in between. Bowl off, fuel line hooked up gas runs, lift float gently with finger it shuts the fuel off fine. Put it all together gas runs, tip the carb over and the float closes and shuts fuel off. I am just stumped. Thinking the float is rubbing against the bowl but I can hear it open and close when rotated. Two sets of valves and seats, two floats. I'm just going to have to try and find some that works on small engines that knows carbs.

I went through a similar problem on my JD 120 with the K301.  4 rebuilds and the final rebuild was done under the watchful eyes of a carb guru in town.  He assured me I was doing everything correct.  

After changing the oil 4 times because I could not get the float right, I swapped in a Kohler/Carter unit (26 in my case but you really need a 30) and have not had a problem in 4 years.  I am in the process of converting my 312 over to a Kohler/Carter unit.  When it comes to Walbros here is my thought - they either work right or they don't.  I'd say you have one that does NOT work.
