i would check out the parts diagrams here:
if there is no fuel screw, then i'd get an aftermarket one. then pull the main and pilot jets. see what they are, then set them to what is recommended for your altitude.
most guys from 0-4000 ft will run a 165 or 168 in the main, and a 45 or 48 in the pilot. the starter and leak jets are in different places, but i'd worry about the screw, pilot, and main first.
make sure the carb is clean too.
good luck, and keep posting after you make some changes.

you have to remove that to get access to it. you put a screw in the plug, then yank it out with pliers. The part number on the yamaha website is 5NL-14105-00-00 PILOT SCREW SET.
Check out the sticky at the top of the page.
