O-ring..... Carb Leaking Gas

Ok, so I have the usual carb pissing gas out of the bottom of it......I have mine apart looking for this o-ring that everyone talks about that is the usual problem.

Where the heck should it be, Im a noob at this, I've looked over the parts manual and Im not seeing anything.

Thanks

The oring is under the float needle seat. Parat of part #25

That's what I thought, just I couldn't find a way to get it out.....

Thanks for the clarification tho.

Take out screw No 26 and the float seat will just pull out.

Instead of buying the whole float needle set for $50+, I replace the o-ring for $0.50 and solve the gas leak problem. After you take out the float needle set, inspect it and figure out what needs replacing. Most of the time it's only the o-ring that needs to be replaced. However, Yamaha do not sell each piece individually. Go to a reputable motorcycle shop do repair and they should be able to sell you the o-ring for under a buck. That's what I did and thought I share.

If the shop you go to doesn't have it, they can order it from Sudco.
