Do you mean that if you take the black cover off,and the separator plate out, that there is not a piston in there with a connector link internal to the device?
If that's true, then that is the wrong carb for Norway,lol.
Also if it's true, then to the OP; I'm sorry man, I messed up, and I have never seen a carb like that. And IMO, if I couldn't convert it to some type of pull-off, I would get rid of it.A carb has to have a choke pull-off of some type.
