Can anyone tell me which screws on a carb are the slow speed ones and which are the high speed valves? I have a 1999 Yamaha 115tlrx. She runs great at WOT but when returned to idle, she idles very rough. When a push of the key choke is administered she smooths out a bit but returns to rough idle. I know its running "lean" at idle, I just need help identifying the s/s needles. Thanks
