I tracked some down and followed the no.9 rule and set them all with the feeler guage and wow it sounds different! When I come off the accelerator it doesn't make much noise as it did before and I thaught I was stalled at the traffic lights I couldent hear it with the radio on low.
It was a doddle to do and made big difference. Thank you James Martin and lynall for your helpful advice - you both allways help!
Cheers, tom.
