Half way run in

Yesterday I took a nice long easy drive past Stockholm and up to Norrtälje where Neil has just bought himself a house. The temperature was only around 5oC so had to wear a few layers to keep me warm. I didn't bother with the roof or doors so there was a bit of a breeze! It was actually fantastic getting out again even though I took it really easy, it's so nice to drive a long country roads during autumn, past lakes and forests. 

There and back was around 240km so I'm up to just under 500km (300miles) for the running in.

It was still running a little rough and stalled almost every time I had to stop for something. When I got home I checked the for leaks around the inlet manifold and everything was tight. I checked compression again and it was better than before. All four cylinders where over 16 Bar. At the same time I checked the spark plugs and all were showing signs of the engine being too lean. I'll talk to Henrik about it as I don't want to do any damage. Perhaps he will suggest tuning before going any further.

Grey, signs of a too lean mix or is this normal in an injected engine?

The fuel consumption also indicated it was a little lean. Just before the engine rebuild it was doing around 16 litres/100km, not surprising really with broken pistons. On my best ever day without the SC I got around 7 litres/100km. Yesterday it was also down to around 7, which I think is a little low - great but a little low!
