Topic: 1981 CV carb float needle question

[wanackg]

Are the float needle seals on these carbs just small o-rings? I've got a carb overflow problem and I need to know whether to get a full carb rebuild kit or just the o-ring kit. Thanks for any help in advance.

float needle seals?

[wanackg]

there has to be a seal to keep the gas from flowing when its not supposed to, right? or do i need to replace the whole float needle?

[phil71]

no seal, it's a cone, and interference is all it has working for it.You can clean them up, there's TONS of info about how to do that. If it's a rubber tipped needle, it may need replacing.

[wanackg]

Oh ok. Thanks for clearing that up for me. Guess ill order a new needle.

wait, before you spend money, you should try finding the actual problem. Those things don't go bad all that easy (but they do go bad). Look around old threads about how to clean those parts up so they work again.

Clean your carbs and check your float hights first. Some times it's crud hanging out in the float jets. A good blast of brake cleaner should work that out (if that is your problem). There are plenty of threads here on cleaning carbs.

There isn't a gasket for the float needle but yes there is one for the float needle jet. I have had one go bad on my 86 gsxr11 and it did cause over flow issues. Jet kits ain't cheap so clean and adjust first (plus float jets don't usually like to come out). I use jetsrus.com for almost all my bikes. Very fast shipping.

PS; Those new plastic egg cartons are very handy for keep all your individual carb bits in order.

you don't mean needle jet, or I don't think you do, you mean the seat. The seat may have a fiber washer for where it screws into the carb body, or if it's clamped in with a "C" clamp and screw, it has an o-ring around it's circumference to stop fuel seepage

Yes, the seat is what i mean (brain farted on the correct name
