Poulan Pro - How do I adjust mixture screws?

Or, you can take the ink refill out of a BIC pen and it fits perfectly over the splined screw.

I bought a "spare parts" 42cc Poulan Pro that is only a couple of years old. I believe the only thing wrong with it is that it needs a new gas cap because the old one has swelled and was mutilated so air could not get in. Now that it is running, it idles way too fast even backing out the idle screw all the way. In addition, when I open the throttle fully, it dies. Looking at the mixture screws, they appear to be way backed out but they are not slotted and I see no way to turn them in or out. Does anyone know what tool I use to adjust the mix screws and any basic procedure?

search amazon for poulan pro carb adjustment tool. it is the fine spline one or you can buy a kit with all 6 tools and a nice case for 21 bucks

Or watch this video at about the 3:20 minute mark. He uses a crimp on electrical connector on the end of a screwdriver. I tried it, and it works great!
