Screws in airbox - Yamaha 2 stroke 90

The screws for my airbox keep rattling loose on my Yamaha 90 2 stroke. These are the long ones that hold the air box to the carbs.

Had the carbs cleaned this summer, never had the problem before they were cleaned.

Is it typical to put loc-tite on these screws?

Yes! Use lock-tite for sure…you don’t want them getting sucked into one of the carbs if they come out!
