Can you ID the carb on this DR Trimmer/Mower??

I picked up an old DR Trimmer/Mower (model 4010954) with a B&S 4hp (model 122707 type 0185-01 code 92100756). Without removing the carb (I don't have new gaskets yet) can anyone tell me the carb model #. I'm trying to see if the linkage is as it should be.

The linkage is right from what I see.

I just found some sites that show how linkage functions. I have to study it tomorrow and get back with you. It seems that the carb is not choking. I'll let you know.

Looks like the choke is the large uppermost lever. Hooked to the choke is a cable that is attached to the back of the engine. Should be a knob to pull on the handle to choke it. It is a manual choke not automatic.

I had previously replaced the throttle lever on the handle with one I found laying around. I think it operates properly but I did not have the old one to compare it to. If I push the control forward the cable extends. All the way forward SHOULD be choked, correct? But it does not choke. Almost all the way forward it will run after putting gas in the carb. Pulling the control BACK at all shuts it off. That shouldn't happen I don't think. These pictures are lousy. When the wife brings the camera back I'll get some better pics. In the mean time I will remove the control cable and putter with it manually and see if it starts to make sense.
By the way, the number on the base flange is 2732. The is also a "LMS 31" or "LMS 1". Pretty sure its "31". Don't know which is the model or if either are. Can't find either on line.

The choke is operated by the black plastic part on top of the carb. When the control is moved to the farthest ful throttle position, the little metal lever near that black plastic piece will hook it and turn it enough to close it. If not, the metal lever is possibly bent.

Cheese,
Yes, I think the metal part (that has 2 little fingers) is bent (PHOTO 1). And I need to manually move the plastic chock lever to get the figure to grab it. The finger fits the shape of the lever perfectly (PHOTO 2) but I do believe it is bent. What point is the finger supposed to push on (PHOTO 3)? The only way the choke is fully closed is if the finger pushes at point #1 (PHOTO 4) and this is only possible if I manually move the choke lever to where the finger can grab it.. And I do not see that the lower finger does anything at all.

Problem solved.
I stumbled onto this video that shows my choke and the little finger, https://www.youtube.com/watch?v=q0I7i81Xc3w
The choke is activated at 8:46 in the video.
So I bent the finger (carefully) back to where it should be. The little finger just barely touches the chock lever, but I guess thats all it takes.
