Initial settings for your carb are; 1&1/2 turns out from lightly seat for the high speed needle valve. That is the one coming in from the bottom. 1&1/4 turns out from lightly seated for the idle needle valve. That is the on the top. I would first remove the nozzle going down from the top and make sure it is clean. After you have it running, at full throttle, adjust the high speed needle in until the engine starts to bog and then out 1/4 turn. Then go to idle speed and adjust the idle needle in until it starts to bog and then out 1/8 turn.
