Howdy Bck:
And welcome to The Forum!
It would be helpful if you would fill out some of the "Profile" info so we could know you a little. I particularly like first names or simple nicknames to call folks by.
Our your carb, look on the side of the float bowl under the accelerator pump rod. You'll see a cast on circle with a three digit number in side the circle. Maybe something like "1.23". Report back with the number and I can give you details.
What ever it is it can be adapted to be used on a 200. A 1.23 is rated to flow 356 cfm. It appears to have an electric choke and automatic trans kickdown armature.
Tell us more about your 200.
Adios, David
