Draw length and weight are 2 seperate things. Your weight is adjusted at the limb bolts. What will change is arrow speed (FPS), possibility of change in arrow spine and arrow length
I took my sons bow in today and we had to lengthen his draw 2”. What effect will this have on the draw weight. I forgot to check after the adjustment.
Thanks
Depends on the bow; what model is he shooting?
Most "grow-with-you" bows will have a draw weight dependent on the draw length.
For example, the Hoyt Klash has a draw length range from 18 to 29 inches and a weight range from 18 to 70 pounds.
In the draw length of 23 inches though it will be a minimum of 32 pounds and maximum of 60 pounds. So, each draw length has a given range of draw weight.
By adding 2 inches to your son's draw length may very well have changed the draw weight, but probably not by much; maybe 4 to 5 pounds.

Does a longer draw length give a faster arrow? Assuming the weight is the same.
Yes, this is due to having a longer power stroke.
Let's say your son's bow has a 6 inch brace height and he is shooting a 20 inch draw length; that is a 14 inch power stroke. Now we make it 22 inches and he has a 16 inch power stroke. If all else remains the same, a longer power stroke will yield a faster arrow.
