Ever been at the track and forgot your piston stop? All you need to do is remove the glow plug, run the piston down to the bottom of its stroke and and thread some heavy twine (kite string will do) into the cylinder. The twine will then act as a piston stop and will not damage your cylinder or piston.

what is a piston stop?

a tool that hold the piston at bottom dead center so if u need to remove your flywheel or anything like that :thumbsup:

Man oh Man Hankster. I needed a piston stop the last race of last year. Great idea.
