There's a huge amount of rubbery compression ahead of that, from the air filter between the housing plates.

8 bolts are extremly strong in tension. Yoy would strip out the threads in the carb long before you'de reach the tensil strength of the bolt.
I've made the mistake of using grade 8 bolts in places where they don't belong. Like the air cleaner. Or as part of a stand off. Over time the vibrations will cause the bolt to fracture due to lateral stress. Don't say it doesn't happen, I'v seen it/done it. Then you get a "light bulb" revelation. Switch to a 5 or all thread, and they never break.
Just one of little things I'v learned over the years.
Good decisions come from experiance. Experiance comes from bad decisions.
