Today I reamed a sticking valve on Mellinium cylinder with 250 HRs. There was only carbon in the reamer and the valve stem had some bronze scuffing. The valve and cylinder look perfect with a scope.
I only use no alcohol mogas and lean ROP. Oil is XC 20-50 and camguard. Plug insulators are white and Pmag checks on ground and air are no differenc.
So, what is the carbon source, CAM GUARD ???
