Popsicle sticks are for popsicles. Sounds like you need a new smith. On the other hand, are you saying that he used a popsicle stick as a shim because the hole was drilled in the wrong place? If so I'm still thinking you need to find a new smith because there are a lot of better ways to have made a shim. As to the effect on accuracy, shooting it will tell you something and shooting it over time will tell you more. Shoot it and see how it shoots. If good ok. If not back to step one.
