Choke?

My 88 mazda takes forever to warm up and get running properly. I'm thinking the choke may not be working? I had it the air cleaner off the other day and theres a linkage on the carb thats not hooked up...is that to set up a manual choke or is it something different?

If you take off the air cleaner right after running and with the engine warm, you can immediately tell if the choke is open or shut. If the two plates over the barrel are shut, your choke isnt opening. If they are open and you can see all the way down to the butterflies, then it is.

Now, if the choke is still open when its COLD, that means someone disconnected the choke and thats why a) you have a disconnected linkage and b) thats why its taking forever to warm up.
