Darryl Posted December 5, 2011 Report Share Posted December 5, 2011 I own a 2010 CTLS. I am experiencing severe vibration in my engine when I pull off the throttle for descent - otherwise the engine runs fine. This vibration starts at about 4700 RPM. The run-up is fine. There is plenty of power for takeoff and it cruises just fine. My mechanic replaced the carburetor floats thinking that was the problem. That didn't help. Any ideas?
