Good morning. We experienced a new vibration yesterday. My question is can out of adjustment valves cause extreme vibration at higher rpms? Have never adjusted the valves but runs fine. It sounded like chain sliding in the locker but unfortunately wasn’t. It comes and goes but more at cruising rpm. Almost sounds like valves clattering? Is this a thing in the 120 Lehman? No changes in oil pressure or power. Kind of lost here. I’m gonna to do a thorough inspection today but in the water so can’t check outside prop or bearings. Any help appreciated. Terry
