Plugs have red oily stain and misfire

[zukitrek]

Yes gas color is totally unrelated to spark oil problem. Thanks for all the info. Revealing age is also no problem. i wish I could be like you and a lot of people I know that even after "retirement" are always doing something and keeping the mind in use. I think I found the aux valve holders from a donor head along with ignition and fuel pump. Yes they unscrew making the removal very easy without removing head. And yes they are no longer available. In the days they were $20 a piece. Pump and gasket are the same as at least 10 years, never replaced. But I guess all sparks would show some red color, but no, cause oil is not getting in them just cylinder 2. So my guess is problem is here:

   

You see most of my red oil is in the thread of the spark. Reason? Maybe fuel which comes from the top (green arrows) gets mixed with oil coming in from bad seal-valve guide-o-ring-copper washer etc. So Ill drain oil, remove pump and do a visual inspection then report to you.


Have a great day.
