Welcome back troyp,open the needle valve 2 to 2 1/2 turns,start the engine,give it 3/4 to full throttle,the engine should be rich and 4 cycling,pinch the fuel line if engine speeds up,which it should then lean the engine,screw in needle valve, continue doing this until when the fuel line is pinched ,nothing happens,that is max,richen the engine so when line is pinched the engine rpm goes up 300 to 500 rpm ,after high speed is set,check low speed ,go fly
