Ball bearing in Float Chamber?

So one of my float chambers has started overflowing (62 TR4 on SUs). Suspecting a bit of crud blocking something, I've removed the chamber for a bit of a clean, and found a very small ball bearing in it.

Can't find any reference to it's being supposed to be there in any of the books, but having once been left stranded at the side of the road after having dismissed an important part as a foreign object and chucked it into the tall grass (!), I thought it best to check.

Should it be there? I'm pretty sure it was what was causing the overflow, being wedged between the float and the side of the chamber when I took the cap off.

Thanks!

It fell out of your Grose jet.
 
:lol: That was my reaction too!! Some poor DPO lost one of 'is (GrosseJet) balls. :wink:
 
Just so they both don't get loose on you...then you have trouble in paradise.
 
Whether it's a Grose, or not, the little ball bearing came from the needle valve -- which situation perfectly explains the symptom he was investigating: overflowing float chamber.
 
Thanks chaps, glad I asked. I put the ball back between the needle valve and the lever whence it came (there was only one - assume that's correct for the valve? Looked to be the same on the other float bowl), and then proceeded to strip the threads on both the float bowl stud and nut in putting it back together.

Having had the good fortune not to chuck the ball into the grass, I then overlooked the washer that had fallen off the bottom of the stud when I removed the bowl, and stripped both threads trying to tighten it enough to stop the inevitable leak from under the bowl, caused by the missing washer.

So new parts are on order to put it all back together. (Yet) another lesson learned!

Thanks for the input.
