pilot jet adjusting?

i had my dealer adjust the carbs on my 08 teryx and it seems like it is a tad rich while at idle.they said he adjusted the pilot jets and that was it...anyways after it idles for around 3 minutes it will start smoking black smoke and then i can rev it up and it will clear up.any ideas on how to fix this myself?where exactly is the pilot jets?

Could only exchange out pilot jets.
I'll go out on the limb and assume he meant air jets, which are the jets on the bottom of the carb, not fun to adjust....unless you have a 90 degree screwdriver, only other way is to take the carbs off to adjust the screws. But I would say that is what he adjusted. My guess.

Pull the carbs and turn them all the way in (just finger tight...not TOO tight) and then start with 1.5 turns out...and go from there...

Technically they idle fuel mixture screws, turning them in cuts fuel off.

1.5 is a good place to start for sure.

With our kit we recommend two turns and with pipes three

A good rule of thumb is if your a +3 turns out on your air screw you should go up to the next larger pilot jet size.

Hard to say but the main jets have no effect on idle.

You may wind up getting a air/fuel ratio gauge and you will know as soon as you connect it.

Also, anyway the choke on one carb is stuck slightly open?

Had that happen to me and drove me crazy till I found it.

Yes, that is right. They are a real PITA, once you get used to taking them off (carbs) and back on it becomes quite easy!
I used to spend about 5 minutes taking the carbs off/on Yes...I can do it that fast (after 500 removals I should be able to), until I found my 90 degree articulating screwdriver, now it only takes 10 seconds to adjust.
