edelbrock metering rod sizes

and dont you mean it would be 70 idle and 42 power? because the rods i am looking at running say 7042 and the rods i have currently say 7047, so the 7042's are a tad bit richer then the 7047's on the power side correct? cause the slight hesitation i am feeling is happening right off of an idle or a steady spped, say im going down the road at a steady speed of 30 miles an hour and i go to step on it i'll feel a very slight hesitation same with off an idle. So i'm hoping these 7042's will clear some of this up because its not a bad hesitaton at all.
