Well I've now got to the bottom of the Bad running. Its the Big HG I'm afraid !!!! Dam dam dam!. Basically I found low compression on no.2 and added some oil and re checked it and only a few psi improvement. So off with the rocker cover to check that the valves weren't sticking or the tappets were loose but they were fine. When I got the car I changed the coolant as it was Bright Green. Changed it for the Blue stuff and in the filler cap is some YES you've guessed it Milky Mocha!!!! *astard. Wasn't much but enough to upset the running so next job head off jobby or sell the car as it is. Haven't decided yet although its far to good to scrap or break.
