Depending on idle speed and tslot exposure, is a common thing that a cj style carb can idle with a mixture screw closed.
Is pretty rare that putting an engine in gear stalls due to a rich condition, typically the opposite is true. An engine leans out significantly when a load is placed on it.
If it was one of mine, contact me. If not, why not discuss with the builder?
I would look for outside variables tho. You mention "it used to run great."
This makes me pause and wonder what may have changed, carbs are really feedback devices of sorts, they only really react to given inputs.
Something as simple as initial timing changing could cause an otherwise perfect running carb to become a basket case.
