edelbrock carb question

i have a edlebrock 600 cfm i was getting bog down on quick takeoffs, i noticed on i think its the accelerator pump,the part thats on side has 3 adjustable holes that looks like adjustments to put either get longer stroke or shorter stroke, it was in middle hole i put in lowest of 3 holes what will i get by doing that more gas going into carb or what. it is a 360 with cam and headers and edlebrock intake and about 360 HP will this help or hurt my bog down at fast takeoffs other than that car runs like top? thanks
