BLUE locktite is a godsend and I use it all the time. Engine mount screws, carb screws, fire wall blind nut threads and metal wing screws to name a few.
Just remember to avoid letting red, blue or green locktite having contact with plastic because it can cause plastic to get brittle and crack. If there is plastic like a engine mount, limit the locktite to metal to metal areas such as the head of the screw and engine mount flange or blind nut in the fire wall and screw threads.

It is my opinion that the carb screws should have been loctite-ed from factory, it's a common problem with other brand engines too.
Doing a pre-flight on a cowled engine is not easy, so you learn ways to extend inspection intervals under the hood by making sure things don't shake loose.
The more things that go wrong, the more you (hopefully) learn to how to prevent it happening in the future.
