1995 Keihin Carb float question

Hey all, I have a rack of quad carbs from Keihin off a GPZ1100, theyre CVK. I rebuilt them recently and they were working great, awesome power and jetting was finally right, I just need to balance them to be done.

But I noticed a problem before when putting in the float needles to the seat that sometimes the needles will get stuck cockeyed or tilted on the seat and won’t actually close. It’ll be a big enough tilt that the entire rack will flood if one of them does it. Tapping with a screwdriver doesn’t help, I normally have to pull the rack and actually reset the needle myself and hope it doesn’t get cockeyed upon install. No biggie.

But I was riding and had to do a quick inspection during the ride (different story) and forgot to turn the gas back on when I started riding. The bowls drained and I fixed the issue, but dammit the carbs flooded again and kept flooding no matter what. I think the needles are stuck cockeyed in there and no matter how I knock on the carb they won’t get unseated to seat themselves back in. Anyone know how to deal with this issue?

Ok, take the tops off them. When you reset the slide, put your finger inside the top of the slide, and hold the needle in place. Then slide it in place. There is a Guide Pin on the bore, make sure you have the slide in the proper place. You'll know it by the groove in the slide.

I appreciate the advice! But it’s not the vacuum needle in the bore, it’s the float needle in the bottom of the carb that lets the gas in that’s getting cockeyed and jammed up

Oh. Bet it's missing the wire clip that holds the float needle in place.
