Scooterotica

What magic potion did you use to get that unstuck and out?

I tried various magic potions I'd read about on the internet, coke, vinager, acetone, but nothing was going to shift it even with heat applied so in the end we made a steel insert to sit on top of the piston so that pressure was applied to the sides only (that's the ring on the crown) and put it in a ratchet press. Even then it required a huge amount of pressure to move it and the BANG that came out when it finally starting moving was quite amazing.

Wonder what the tonnage was when it finally moved. 'Kin well done.
