It's the piston return spring bottle clamp, only really used if the gudgeon pin circlip has become entangled in the exhaust valve relief cup.
Under normal operation the handle points downwards. Sometimes the 'head' rotates however you need to be careful of that (sorry to state the obvious but sometimes these simple things are overlooked).
That one looks like it's been used a few times so i'd check the compression ratio's carefully as soon as you can and look for signs of damage on the kettle uplift crank pulley under the exhaust. :drum:
Hope that helps
Naughty, naughty - baiting the newbie.
Well done by the way :rofl:
