omc 1000 creeping forward

[longrev]

I have an omc 1000 and it slowly creeps forward when I have the levers in the neutral position. I have adjusted chain tension, and adjusted the clutches so the lines on the clutch halves line up. Any suggestions on how to adjust to make it stop would be appreciated. Oh, I also adjusted the levers as well. Not a big deal, but just annoying. Thanks, Mark
