Probably as you guessed, leaking needle valves. The overflow
is coming out of the float vents and into the canister.
If you get the soft click but without the overflowing, it
can be a fuel pump problem like a diaphragm pinhole or
a valve problem, but the overflowing canister is a problem.
You might consider taking the canister off while you debug this,
you don't want it to quietly fill with gasoline. Leave the
canister vent line in a safe visible place and watch to see
if any fuel is coming out of it.

They are adjustable actually, just in a different way. The
level determination is the same, and you move them up and
down using tiny fiber washers under the needle valve.

Close the valve with your finger and see if you can blow
air through the fuel pipe with your mouth (a bit of clean hose
will keep your lips clean). You shouldn't be able to blow
air through, if you can, the valve isn't sealing.
If you CAN seal the valve with your finger but it doesn't
seal in operation, look into adjustment.

Loosen the carb bolts, give everything a good shake, then
tighten again. Someimtes the little connector shaft gets
"bound" between the carbs depending on how everything
was tightened. There is a little play in the mounting
of the carbs, and it can line up badly or squeeze
on the middle.

That is correct. The end of the choke cable is fixed, it
is the "shield" that moves when you move the knob. The shield
goes up with you pull the knob out.
