Interesting!

I should imagine I might have come accross this issue myself.

But when I got my 251, it was totally seized including the carburettor.

So I decided to use one of these, and although the kit didn't include an idle jet, I used everything else including the float needle and seat!:

Very true. I think it might be worth persuing though just to see if the wear is really doing anything- after all, I have a few 'high' mileage vehicles- and i've never renewed the carburettor components.
The only reason I did so with my BVF 30N3 was because it was unused for 13 years and the jets were all blocked up. It took me ages to clear out the channels in the carb and get the idle jet clear (once again- I don't know why that wasn't in the set).
