Mike,
If you’re starting with a clean carb, cleaning it with carb cleaner will work well if done at the end of the session day. Don’t have an ultrasonic cleaner, but it probably is the best method.

Make sure to remove the needle valve before you spray the carb with brake clean, or you WILL have to buy a new one.

Yes! Always make sure to remove the needle valve when cleaning.  I’ve toasted two engines in the past by not doing this.  Also, soak a q-tip

with wd40 and swab the needle valve seat before replacing. This helps initial lubrication of the seat. The carb cleaner can dry out the seat potentially causing the needle valve to stick during startup after cleaning.
