Plugs were black and sooty. They are IK27s gapped at .6mm. I'm on standard ignition and coil. The tip of the centre electrode did seem clean however.

Plugs didn't especially smell of fuel, nor did the cylinders, and nor did the exhaust (this is the only time I've checked them since I changed the chip yesterday though, so since I just changed mixture screw this last time, it may have leaned it out a little, and the blackness may have been from previous rich mixture)

Have left plugs out for now in case it does need to dry out a bit

I did pull out the dipstick and the oil does have a petrol smell to it...hmmm....just did a change too - again this could be a result of previous rich mixture

So either way, the last time the car was started, it smoked and missed when the accelerator was pressed, but seemed to idle ok, even though it idled at about 1500+ RPM as it's about 6 degrees outside and it was cold started - and I shut it down after about a minute
