This is an AMERICAN MADE piston stop for service that requires holding the crankshaft in place. It can be used for clutch service or flywheel nut removal or servicing weed eaters and leaf blowers. Just remove the spark plug and screw this tool in it's place and lightly snug it down. Turn the engine either clockwise or counterclockwise until you feel the piston come up against the tool and you are ready to do your service. Remember that most chainsaws have left hand thread on the clutch side. The end is machined full radius to prevent damage to the top of the piston. The tool has a hot black oxide finish. Very easy to use and very handy to have around if you do your own saw or other 2 cycle work.

Free shipping in the continental USA.   Sorry, No sales outside of the USA.
