Hello All,
I popped the head off of my ST45 for the first time this morning and was very surprised to see a dark green tint on top of the piston and on the head. I'vebeen using Cool Power 15% most recently. Is it normal for an engineto take on the colorof the fuel it is using?
SORRY! I'VE OBVIOUSLY SELECTED THE WRONG PHOTO. WILL TRY AGAIN
