The original CC Racing often copied but never duplicated Needle Clamps. I designed these about 10 years ago and every fly by night backyard company on the market has copied them, but very rarely have any of them got such a simple design right. No more need for the ugly fuel tubing and zip tie. These clamp on the needles of wt257 or the new wt1048 carbs and stop your needles from coming out of adjustment. They come black anodized and fit very snug on the needles so that you do not have to overtighten the screws like some of the copy cat needle clamps on the market. You use the same flat head screwdriver to loosen or tighten the screws that you use to adjust your carb.
