wassell carb choke question

[chaz]

looking to try a new Wassell 9/30 carb. as the old Amal didn't have a choke the old choke cable hole was filled with mastic.
can I get away with the same sort of thing and would I need to remove the choke slide and spring?
the Amal has a plain diameter for choke cable ferrule but the Wassell has screw in adjusters. means I have to make new cable

You could drill out the thread and use the original top hat ferrules.
The adjusters cause the cable to have too tight a bend.
