If you want to seal your engine for precaution, then put some sealant by the carburetor neck before installing it into the engine, do not use too much, all you need is a little bit, and wipe off excess, just make sure you do not let any of the silicone sealant material get inside the engine.
ps. The carburetor neck is the only place you want to put silicone.
