That will richen it up a little bit, but you might need a fatter pilot. How many turns out are you at right now, on your screw? You should be between 2 and 3 turns, more than 3 you should go one size richer on your pilot, less than 2, go one size smaller on the pilot. ;)

i think i'm right at 2. so it's OK to go to 3 turns out?

Or any air leaks for that matter. Make sure your carb is lined up correctly.
