Default excess fuel from front carb needle jet at tickover?

hi there foks,

while having a general tinker with the bike at the weekend I decided to balance the carbs. while the bike was nicely warmed up and just ticking over i could actually see fuel coming out of the needle jet on the front carb but none coming out of the rear. I've noticed this before and didn't think much of it, but it's fresh in my mind now so i'm asking for a bit of advice.

is this usual on a curvy? or is it likely i've got some gunk up there that's stopping the needle seating correctly on the front carb? I checked the position of the circlips on the top of the needles recently so i'm sure they're correct. doesn't seem to affect running or fuel ecomony (typically 140 to reserve commuting) but it does pop occasionally and sometimes you get a wiff of petrol.

Had a look in my carbs to night charlie and sure enough there's a little spit of fuel when she's ticking over from both.

What position do you have your circlips on the needle in? I read if have it one way it's richer and leaner the other. But not sure where to put my washer circlip if honest..
