Strange Jubilee Choke linkage

My "new to me" Jube has a strange (again, to me) choke linkage & I was wondering if anyone has seen one like it & just what it is. The choke button is mounted thru a hole in the cowling below the steering wheel & pulls a "crank-shaped" linkage that mounts above the battery. The choke lever on the carb is flipped down instead of up and pushes instead of pulls the choke butterfly which is mounted over-centered so it works this "wrong" way.
I'll try to post some pics.
 
Pics didn't work. I'll try again & also send them to Royse. He volunteered to post them for me (thanks Royse!).
 
I sounds like someone put the choke butterfly through the choke shaft in the wrong orientation. And then they went around the world to make it work instead of fixing it right.
 
Here they are Lynn.
Den is right, the butterfly is in backwards, but your linkage
makes it look to me like it was done on purpose!

Thanks Royse! As you can see in pics 1 & 2 the choke knob is just below the steering wheel. Pic 3 shows how it pulls the "crank" & transfers to a pushing on the carb side. Pic 4 is that side.
Looks way too well designed & made not to be an aftermarket. (IMHO)
Any ideas?
Thanks

Lynn;
I'm with Den on his assessment, of what is going on with your carb choke.
I have seen the carb pix, and that is what I am seeing!!!!
If I were you, I would ask Royse, to fix the choke properly, on the carb and get the right choke rod set up for yer Jube!!!
Better off than waiting until something goes wrong, or breaks, with that choke rod the way it is working now!!!

JMHO....and, I,ve seen a lot of things done to carbs, and workings, that may work for awhile.....then, cause problems, down the road!!!!

Gosh it sure does look manufactured not a homemade barnyard fix, im almost wondering if it could
have been part of the adaptation of something like a funk kit or some other early repower kit, then
maybe the parts later found there way onto your tractor, or the engine was put back to original
type and the linkage just adapted.
 
markct, I agree that it looks manufactured. Even the 2 "tabs" that mount it look specifically made to fit. The whole thing looks like it was made to just bolt on, not bolted on & made to fit (like something I might make!) I'm still hoping someone else has seen one!

If you could look at enough antique cars, I'll bet you could find that 'bellcrank' assy. I grew up in my Dad's junk/wrecking yard & remember similar.
 
It would make sense for someone with physical limitation to move, or have moved, the choke knob. Short arms (young person), someone with other limitations? No reason that I see to do it otherwise.
ps Using my old handle until I can get "John in Mich" restored.
 
I was thinking along those lines too John.
But honestly with the original set up you can push the thumb
button to start it with your thumb and pull the choke with the
fingers of the same hand. Only one hand required to do it all.
So what came to mind was a neighboring farming family here.
They have all lost fingers due to farming accidents.
Every one of them in at least 3 generations.
Maybe something like that was the reason?
 
I have 2 Jubilees and have started them that way. If a person was missing fingers, a hand or a left arm, that won't work so well. Put the left foot on the start button and use the right hand to pull the modified choke location appears to be ingenious to me. Again, I don't KNOW why for sure but "could have been". Other ideas might surface but I doubt it was done just for something to do.
 
I was hoping someone else had seen one like it and could identify it for me. It's just different enough (& looks pretty handy!) that I plan to keep it anyway.
Thanks for all the responses!

Hey Lynn I finished up your carb today, just need to get out one
of my Jubilees to test it on and it will be on its way back to you.

Here are a couple of pictures of how the choke is in there.
Before and after just to make sure I put it back the way it was.
Minus a little rust and dirt of course! ;)

Nice work Royse. After looking at that and again at the pictures from Lynn, I wondered if maybe the person who made that modification was a past 8N/9N owner and just liked that location.
 
Thanks John. Sometimes modifications like these make me wish
these old tractors could talk. It appears to be quality work, not
cobbled, just set up for the person that wanted it that way.
We will probably never know why as that history is likely lost.
All but the tractor itself of course.

I can't pull it out of my rusty memory, but I've seen similar too.
gas pedal linkage maybe.

Under the gas tank on some Farmalls, there is a similar linkage, though smaller.

Operator of this tractor maybe just wanted to use his foot on the start button and needed the choke higher.
Lots of other brands use your foot to start them.....old habits are hard to break.
If it works, it works. Not a bad idea really. with 15 layers of clothes on in January, bending that far over to hit the button and pull the choke is tough :D
