SHE'S ALIVE! Motor runs strong and smooth but there is a problem.. at idle it is pretty rocky but holds idle just fine. feels like a small earth quake inside. As soon as I give it gas it revs really nice and smooth. Any ideas guys.? Here's a link to the 1st start up. You could hear the rockers slap than fade away.

I use Champ Copper Plus RC12ECC and like them. Never had a problem with misfire.
