The mixture adjustment screw is located on the top of the air cleaner behind the wingnut. Look for a black grommet with hole in the middle. You'll need a 3mm allen wrench. Stick the allen wrench in the hole
and push down until the wrench catches the head of the spring loaded screw and turn the wrench slowly (depressed while turning) not more than 1/8 turn at once and then remove wrench. Start the car and rev. it up
slightly for 15 seconds. Take it for a drive and see how it runs. If it feels a little better you might want to try another 1/8 turn CW. Your idle might need to be adjusted down as this will increase your idle a bit.
If it runs better, your done.
If not, turn the adj. counter clockwise back to where you started, be as precise as you can
