After talking to Lord, the indication was that I had a mount (top passenger side) that had run its cycle. I couldn't get a good answer on what the lifetime of a mount should be. I assume there's too many variables. I also don't recall checking the cure date stamped on the box when I originally mounted the engine three years ago. I'm guessing that Vans stock may not be the "freshest" in that regard. I got new mounts installed and the extra shake and "knocking" at idle and shutdown is gone. I can't believe the difference. I noted that even the "new" mounts I purchased from ACS had a cure date of 1/2015, so even they were over a year old in the box. Anyway, I'm a happy camper now. -Sean #40303 (shake free) > Sean Stephens > June 17, 2016 at 3:37 PM > > After testing the other night at the hangar, the idle mixture was too > rich at about 150 rpm, rise.
