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)

For light-duty engine work, the piston locking tool included with this
tool is all you need to prevent the crankshaft from rotating. To use the
tool, simply remove the glow plug and screw the tool into place to hold
the piston at bottom-dead-center.
*** Do NOT use this type of tool for heavy-duty tightening or loosening
as you may overstress the piston, conrod, or wristpin. ***
