I had the same problem on my 2185 after doing some carb work, way back when I first got it 4 years ago. As I recall, I just had to loosen the cable clamp and let some slack out. I had 1st adjusted it at either WOT or closed which somehow limited travel. Now it is adjusted by mid-throttle on the dash, giving a little extra travel at both ends.
Anyway, I went out and looked at my 2185 and then looked up the picture which is attached from:

I think you need a cable adjustment, mine is very close to the picture from the pdf and runs properly, your the throttle lever is turned quite far to the right.
ETA: I found that outmost hole on the throttle lever gave the best travel at the instrument panel, and that 3rd hole from the end on the sensitivity cured the governor surging.
