Who makes the carb? Mikuni? We need to know more. I'll assume that its a 2-stroke.

If there is someone here who has direct experience with 2-stroke carbs they might be able to help, but the quickest answer is a motorcycle or ATV shop. Just go straight to the garage bay and politely ask your question and you should get an answer.

There should be three screws in some fashion. Most modern 2-stroke carbs have a high jet, a low jet, and an idle setting. Sometimes the idle is set by simply using the throttle cable adjuster, but not usually.

Also are you sure you're looking at the right fuel lines? 2-stroke carbs have multiple overflow and air bleed tubes that are clear, but the fuel line itself is black rubber. You won't be able to see fuel in it. Pull the plug and see if there is gasoline on it. If there is, you're definitely getting fuel. Hold the electrode of the plug against the metal of the engine and crank. See if you get a hot spark. 2-strokes notoriously foul plugs because they burn oil with the gas. Also, if you foul a plug or flood the engine, don't try cleaning it or burning the gas off... just get a new plug. Ignition systems on newer cars are really hot and they'll send a spark no matter what the plug looks like, but 2-strokes are barely making enough. If the plug has been flooded, has carbon on it, or just looks "used" try a new one. They're $3, so its nice to have a few spares on hand.
