The solution to the perculating/leaking flat fuel bowled Eddy carbs is an electric fuel pump. I added a cheap carter electric pump in series with a carter mechanical pump years ago. Turn on the engine hit the prime switch until you hear the fuel pump noise change and hit the starter. The 440 then starts like it was fuel injected. Eliminated the hard hot starts and the cold hard starts. An electric fuel pump covers up many carb design faults.
