you dont have to take the site plugs allthe way out just loosen them up till their wobbly if gas comes out screw them back in and adjust the float down then do it again till no gas seeps out.now you can remove it and make your adj. without a big mess.but as was said i would check needle and seat first if its been sittin.and remember clockwize lowers counter raises your fuel level.(thats the one i always forget).
