Isn't the problem pretty obvious? You've got one too many carburetors!
LOL Your fondness for dual carbs and cats always cracks me up.
I'm told the jets in a 2G will fit so if you find some cores laying around you might find matching pair. I bought my carbs at a flaps and they were done by Canada's biggest? rebuilder. They were $90.00 Canadian w/$50.00 core and were good to go out of the box.
