OK, lets see if I can make sense here. You could check it several ways, but, with the engine running, the pulloff will pull in the linkage on the top left (from this view) in until the choke flap opens about 1/8th inch or so.
Or, without it running, Push the linkage(the part with the screw & spring on the end) into the pulloff canister and hold it. Take a pair of pliers and squeeze the vacuum hose closed, and hold it. Now let go of the linkage. If the vacuum holds the linkage in, it's good. If it comes back out, it's bad. I'm not good at explaining things like this, so I hope that made sense.
