Hi Dieseldog

He believes that the oil could be too thin. 5W40 and running just at 1.2 bar at idle. Another thing I just thought of is that I put some Copaslip (antiseize) on the plug threads before screwing them it. Maybe this is insulating the grounding? I will be checking the resistance of each plug wire. This is a regular misfire I can hear in the exhaust. Do you think I should be checking valve clearance too?
