It's not clearing up on its own and gas was fresh from the pump (ethanol free). It's not a lot of white-ish smoke but certainly noticeable and enough to show that something is not right.

You guys are fantastic! Thanks a lot.

I put in Trufuel just to make sure. Same thing - still smoked when revved. So I left it running - after 15 mins same thing. About 30 mins - completely clear smoke.

Thanks again.
