My other thought is to have my distributor reconditioned for which I have been quoted approx £100, but again I dont know if this would help.
I have bought a new timing light and at the moment retarding the ignition one degree at a time and now at 6 BTDC with both vacuum pipes off and plugged. Better, but still pinking on load, maybe one more degree will do it!
I did yesterday forget to refit the pipe from the manifold and drove with it still capped off. It seemed to pink a little less than when connected to the distributor.
Can anyone tell me if this is telling me that there is something wrong inside the distributor? Is it ok to drive with it disconnected and plugged off?

Are you able to let me know what distributor you have in your Volvo? The last 3 numbers of the number on the side of the distributor. Yours has 2 vacuum units, does it?
You could be experiencing one of a number of problems there. A couple intial checks would be as follows:
- Check the condition of the vacuum units. Do this by sucking the pipe and making sure they maintain vacuum pressure.
- Check the condition of the mechanical advance by taking off the cap and grabbing hold of the rotor arm. You should be able to twist it with reasonable amount of tension, then let it go and it should spring back to its original position. If it won't twist, it's jammed and needs lubcricating. If it's floppy, you're in trouble because the individual parts are now obsolete
If you could let me know the Bosch number, I can find out if it is possible to repair it. However, it's possible that it is too far gone. Seeing as you're having to retard the timing to stop pinking, my guess is that your springs are sprung....
This thread I did in the Amazon section might be interesting for you:

@ Arcturus - What have you done with your old distributor? What are the last 3 numbers on the Bosch number and do you no longer have any use for it? Please?!
