Have to cahnge carb and what kind of silicone do I need to use to seal it

Go to NAPA and ask for the red RTV. Put it on the carb neck, not inside the engine opening. Press down hard to seal the O-ring as you tighten the clamp.

RTV (I think that's the name) or sensor-safe silicone gasket compound.

I used Permatex engine-safe (dunno if it's the same as sensor-safe compound) and it seemed to work just fine. Didn't have any adverse effects.

EDIT: Rolex beat me to it.

Do not use any silicon or any "grease" to seal a carb unless you have some odd leak or something. Theres no need since theres an O-Ring

Initially I'll agree with Jay. If you have a fresh o-ring, and are not suspecting an air leak, then don't worry about it. Just make sure you press down to seat the o-ring while you're tightening the carb.
If you think it's leaking, I used Ultra-Copper Sensor Safe sealant.

I just used a new o-ring and I haven't had any trouble out of my T-Maxx with a trx 2.5
