I just purchased a 2010 C190 with 1800 hrs, after a full service and running it for 110 hours I noticed it is not nearly as fast as my 2007 model C190 when in fast mode, and the steering joystick doesn't respond as quickly. Yesterday while in slow speed I allowed the drive stick to return to the neutral position after moving forward and the machine kept going for about one foot. There is also a noticeable delay on both tracks but a little more on the left side. After you move the drive stick (left) there is about a 1.5 seconds however the machine works perfect other than this issue. Can anyone ahead some light on this issue?
