I'm fitting a new pump head on to my Potterton 80 combi...
But I'm a bit concerned about the Pump starter Knob I unscrewed it like the the manual says and pulled it out to engage the spindle but to my supprise it came out of the head all the way and I ended up with it in my hand and I noticed it was splined at the end ( The old pump dosn't do that)...I put it back in again but I can't get it to spin the pump vanes..It just rotates freely...will this be ok???
