I think the main issue wit h an SU that's too big isn't so much the choke size. After all, being a constant depression carb, if you don't have enough suck the piston won't fully rise, so it's a little self-adjusting. What you lose, of course, is the full range of the needle that you get in a carb that's the right size.
