Sorry if I hit a nerve about the metal comment. I do believe the poster has a
lot of experience with small engines and am not trying to discredit him, I just
disagre with his theory and the specific statement. FTR, I did take metalurgy
101, 202 and 303 during my BSME with automotive and fluids minors, which by the
way included lubrication properties/theories between dissimilar metal
interfaces. I will let it drop.
