I've not run a Weber 2bbl on a 194 but can't see why it wouldn't work great with the right jets.
The 32/36 Weber/Holley/Carter carb came stock on the 122cid and 140cid Pinto, perfect size to feed its 105 gross horsepower. So it should be very close on a stock 194/120hp Chev, and get super gas mileage as well.
I ran that carb on my Pinto, got 35mpg highway, 30mpg overall.
