Thanks for all your help guys. I woke up this morning and realised what a twit I'd been. Of course unless the engine is ubnder load or under full throttle, the vacuum will increase the timing.

I'd forgotten that previosly I tested the timing at 3000 with the vacuum disconnected. I will now go and bury my head in the sand for a few days.

All the best over there (bet the weather is better than over here).
