Hi Max,
All fixed the choke was letting too much air through so a couple of pop rivets solved the problem. I tried one pop rivet a couple of days ago but it needed two
This is why I save choke vanes from old carbs here.
Most time small holes works but I have one time where the opposite was necessary on a handheld blower. Original carb hole were too big and the replace had too small of holes. I got lucky that I had a vane with the correct size holes.
Basic I started with a non start condition unless I hand choke the blower and then with the new carb it was flooding on choke.
When I first started working seriously on small engines Tecumseh engine were bad about choke vane holes being too large. It was recommend solder one of them up. But I prefer some more solid like a new vane with smaller holes.
