Can't get the idle right

[JOES31]

The float is good. I had it submerged for 2 days and no leaks. Nobubbles when submerged in water.

The advance arm makes contact with both sides of the distributor. That was the first thing I adjusted before start up.

I will re inspect the cap jet for cracks but I would think it would leak right away as soon as I reinstalled it and turned the fuel on.

Is it possible that all the Zeniths are just worn out from so much use? If so has anyone tried a brand new Zenith or Tillitson from the supply houses?

Getting this thing right is like trying to make the wife happy during childbirth!!!
