Could someone kindly give me a rundown of how to check the engine mounts on a 603? Mine's been vibrating a bit more than usual at idle ... nothing that's knocking me out of the seat, but enough that I'm wondering if the mounts aren't beginning to tire. Could just be the drop in ambient temperature (it's worse when cold and improves somewhat at oper. temp.), but I'd like to give the mounts a check anyway. What do I need to look for and where do I need to look for it?
