Appreciate the info tho. I'd feel better if I could have the idle around 900-1k honestly. but if consensus says 11-1200 is fine, then I'm happy where I'm at for now. There isn't much time left in the season here.
One big reason is my carbs are still capped for the mixture screws. I should of drilled them out when I recently cleaned carbs so I could clean the passageways there. Maybe if it becomes a bigger problem when starts getting a little colder I'll adjust them.
Recommended idle speed is 1300 +/- 100 RPMs.

If you want a smooth idle you need to clean the passages, check the condition of the o-rings, and precisely adjust the idle mixture setting. It's not difficult. Starting at 2.5 turns out gets you close. It's usually set leaner than that from the factory.

You also need to sync the carbs.
