You know? It appears from your post that your engine will not start. Those screws in the front or on the sides of the carbs are visible so you figure: If I play with them, maybe it will start. ---WRONG!--- In all probability, it will make matters worse.
But first, let's use a little logic: Internal combustion engines need three things to start and run: Air; Fuel; and Spark. If all three are present at the correct time the engine will start and run.
Now, let's assume for now that the engine is getting air
Next, since the electical system is the most complex and usually causes most of the problems, let's pull all three plugs and check to see that they are getting spark. Let's assume for now that they have spark.
NOW: is the engine getting fuel? Before messing with the mixture on the carbs, check the fuel system from tank to carb inlet to see that it is delivering fuel to the carbs.
Now, if fuel is getting to the carbs, then we must check to see that the carbs are accepting it BEFORE messing with the mixture. Remove the carbs and remove the fuel bowls. Check to see that the inlet needles are not clogged and the floats are not stuck in the closed position. While they are open, clean the carbs and all passages, reassemble and install on the engine.
NOW IT IS TIME TO ADJUST THE CARBS. Start with the needles 1 1/4 turns open from a lightly seated (closed) position.
Now, since synchronizing the throttle and ignition and adjusting the carbs is a complex procedure taking up 2-3 pages on which I have written before, go back and look up threads on adjusting carbs. Buy a Clymer manual which will give detailed instructions
