Is this nut on backwards?

Thanks fellas.
I tried to remove this last night, there is 1 nut I cant seem to get at though! Any tricks to getting at it? Its on the bottom side slightly to the left of where the 'bowl' for the choke bolts on but you probably figured this is the bolt I was referring to.

Putting this back together looks to be a PITA too.
As I recall, it can be done with a socket and extension. But yes PITA for sure. You just kinda aim the socket at it till you feel it engage. Cause you can’t see it as you do it. I ‘cheated’ putting it back on. Had the engine on a stand... and still dropped the damn thing a couple times. Lol
I guess I need to flip those 2 end nuts on mine. I know I researched it when I did it and apparently got it wrong :(
I may still have an extra brass washer if you need it.
