Thanks Richard. How did you get the picture to upload? I kept getting a message saying that the image was too big!
I'm pretty suer the gap is greater than 1mm ( as per previous post on this thread) I've not measured it but have no reason to assume it has been squeezed down from the original 1.3mm Is that likely to make much of a difference - the car feels like its running well...
I had to resort to some cunning and host the picture myself after grabbing a screenshot. You need a host that will provide you with a direct picture link then use the picture icon whilst making post. I use
Imgur which is free and tolerant of any picture I upload irrespective of file size since it reduces automatically.
Regarding plug gap, I would reduce to 1mm as suggested or 40 thou if you have imperial feeler gauge.
