So I have done the compression test working from left to right 1, 2, 3, 4

Cylinder 1 – 8.8 bar (127.6psi)
Cylinder 2 – 9.2 bar (133.4psi)
Cylinder 3 – 9.0 bar (130.5psi)
Cylinder 4 – 8.0 bar (116.0psi)

So I am a bit low on number 4 – why could this be.

I am super worried about the seal on the base of the cylinder sleeve, not that I have done it wrong, just because I have never done this before. But then that should not have an effect on the compression. Maybe the piston rings are lined up with the gaps?? Just guessing here so any advice would be appreciated.

Otherwise the figures seem OK to me.
