What kind of noise are you hearing. Is it just the induction noise
of ticking noise from the valves?

The way I work the choke on my 78 with dual HS2's is full choke on cold
start up and then push in the choke about half way till I get an idle
speed of around 1300-1500RPM. When the choke is fully engaged the
mixture is very rich and only good for cold starting not idle.
I too had the same problem with the choke cable not staying in place. But
you can put a small bend on the cable where it comes out from behind the
knob. This will place more friction on the inside of the cable and will
stop the slipping.

Are you referring to the dash pot oil? You will loose some oil in the
dash pot if it is over filled. You can see a nice spray of oil coming
out of the top of your dash pot if you rev your engine when it is full.
Check the area under your bonnet where your carbs are, you should see
some oil spots there. That is where your oil is going.
