Yeah I’m puzzled also. I had already checked what you concluded but none of that is happening.You are very welcome. I am puzzled as to why the "cable being tight" is causing less lift for you. A tighter cable is what I created by moving the pin's attachment to a different hole in the lift arms from that what was provided from the factory position. My only conclusion is that your cables are being bound up, or the lifting arms being wedged for unknown reason?
