I miss this type of debate on this forum.....actually haven't seen one since I am here.
In "old" days when 2stroke engines were piston ported (and with mineral oils) ....coffe brown sparkplug was a norm....
Nowadays with X-torq, 2-Mix engines (and with super-duper synthetic oils) reading a sparkplug colour become a little tricky business (at least for me personally)
I screw in sparkplug the way that its electrode doesnt obstruct the flow inside the cylinder.....thats why it looks lean on one side and rich on the other....
I find that funny.....so looking forward for some comments!
So here it is a sparkplug from my stock Husqvarna 450 mk2.....last run was with XP+ syntetic Husqvarna oil @40:1 ish... (before that it was Shell advance ultra 2T @32:1)...
