                    It is a multi-purpose trackside tool.

FEATURES: It is two tools in one, plus a spare glow plug storage.
          The steel shank screwdriver is ideal for adjusting high- and low-
            speed needles, as well as throttle stop screws.
          The machined, blue anodized aluminum handle is knurled for a more
            secure grip, and features a piston locking tool inside.
          Threads on the end of the handle let racers keep a spare glow plug
            handy. (glow plug not included)
