Installing a new carb on a savage 25 should I use rtv ?

Yes, I would. Most people use something like Permatex Ultra Copper.

While you're at it I would seal your whole engine, when it comes to tuning you'll be happy you did. Link below to a very good write up:

Welcome to the forum, post up some pics and details of your RCs when you get a chance.
