Figured out a carburetor problem

You, sir, are determined and dedicated to completion of a task.

Neat job -one question, what model or year uses the bell crank to reverse the pull on the choke? I haven't seen that on any of my D2 carbs. . . I have a time or two pulled on the rope for 5 minutes only to finally remember the damned counterintuitive choke has to be pushed in to choke. . .

Thanks tognot, I am on a quest to complete many long standing half completed projects. Unless I find some more to start.

choke pull, throttle up push. nice job with stops. thanks.

The D2/D3400/D311, D4/D4400/D315, and the D6/D46000/D318 ponies I have been around are normal pull to apply/push to open choke but might be considered backwards on throttle motion. Pull throttle knob out to restrain governor arm and close throttle/push to release governor arm and allow throttle to open. So when cranking it, you would have both knobs pulled out and when turning the diesel, you would have both pushed in.

The later vertical cylinder side mount ponies did have a leaf valve in the choke plate. Not immune to failure, but far simpler than the type you were dealing with. I just blocked off the hole on the D7 48a pony cause the leaf valve and spring were gone. Have to be on your toes and not flood it, but like the horizontal opposed ponies, it does have a drain on the manifold if you really mess up! Just cranked it up after sitting for several years and after dealing with the putty-like material in the gas valve and sediment bowl, the pony ran well. Put fresh gasoline in it for the first start but by the next day I could no longer get any to flow into the sediment bowl, so I poured in a whole bottle of STP fuel system cleaner. By the next day it was flowing gasoline again!

I just went out & started Wilford just to make sure it wasn't a brain fart on my part...& yes, the choke pushes in to close. Push it in while it's running, it starts to blubber & blow black smoke. The arm points down, like your pic, but the rod is straight through from the knob without the brass bellcrank & linkage in your pic. This carb came off of the 5U pony I bought to replace the blown-up original, but it didn't have the bellcrank either...it has the mousetrap thingie that you rebuilt. The pictures in my 3J parts book show the arm pointing up, which would make it work normally-pull to choke. I used the better of the 2 carbs, the original had a mess where somebody re-soldered the choke plate screws to the shaft...
The throttle works just like cc said, pull out to idle down...
Dunno why she's that way, but she is...😕

Corrections:
Appears to be early 22AX8 carbs, early versions with slightly different ear on the 9B4893 "Lever & drive assembly"

Used on the vertical twin cylinder pony motors.

Complications:
The only carb I could find that has the thread option for fuel line connection vertical on the bowl cover is for D7 9G1-9G1129 on a 2B8447 carb but the lever assy shown is a 9B4526 which doesn't look like yours and is apparently not available.
