Small update. I didn't have enough Brake pipe unions to completely delete the damper so It is still in at the moment. What I did do though was Bleed the clutch and managed to get some air out again.
Massive improvement, The pedal is much more consistent again and I feel a lot more confident with it. It still isn't perfect though so I will delete the damper when I have all the bits I need.
For anyone considering the damper delete, you need a Female brake pipe union. Approx 2x 30cm lenghts of copper pipe, 2x male unions and a 20cm length of flexible brake pipe (Can be braided steel or rubber) with 2x female ends. One length of copper pipe replaces the hard line going into the slave and goes round the front of the gearbox, then the flexible line goes in, then the final bit of copper goes to union that was threaded into the damper.
