So - after a few hundred miles of running the 998 auto - just having a look around and checking all is well. Leaks, mixture, odd rattle etc. Plug no 1 is perfect grey and brown, mixture about right I thought. Remainder are all black and a bit sooty.
So - if one is right the mixture is right ?? yes??
How do I tell if it is over rich or oil burning? No signs of smoke from exhaust.
Anyone else had this odd experience?
Thanks...
