I have this 8R6 Briggs on my walk behind garden tractor and for some reason when I put it back together the governor doesn't work now. When I took the engine off the it to restore it, the governor worked fine so I'm thinking I didn't hook something up right. Now, I put everything back as the book states, but maybe I'm missing something or the governor blade is stuck. I am including a pic you can zoom in on to see if I have everything back together correctly.

Check your carb linkage for anything binding

Your picture is too small to be of any help.

 

Look at Figure B20 on page 38 of this manual:

Much better pics!!!

 

It appears you have 3 connections to the carb shaft -- there should only be two.

 

The governor spring and the air vane governor connections are correct, but it appears the throttle cable (?) is also connected there.

 

The throttle cable should cause tension on the governor spring which opens the carb butterfly, increasing engine speed.  ......When the engine speeds is fast enough to activate the air vane governor, it counteracts the spring tension and closes the carb butterfly slightly to decrease the engine speed.

 

When everything is operating properly the air vane and spring keep the engine speed pretty constant, with very little fluctuation.
