Looks like you'll need a choke stove. I think it mounts where those two holes are below the carb. THen you'll need a choke linkage rod from the stove and another linkage for the choke pull off. That will work if your heat riser is operable.
Might be better to go manual choke but then you'll need the correct choke plate croos shaft for your carb along with a bracket and cable.
Another option is an electric choke conversion.
Look in here for all that stuff.
