Mountain road haulin the mail all is fine. Enter the woods, plough around at wlking speed and the engine develops a rpm-synchrone ting ting ting sound.
Whatsthat? Valve clearances getting so much larger that even the buddy idling besides me hears that sound?
N.B: effect wers of with increased speed and decreasing woods work. I'm worried. Anyone know that effect?
edit: this is not a knocking ping, happens most profundly at idle.
