Thanks for the info. I do have ip timing on the list of things to do. I also have a new head and timing chain, so those two are out as possible suspects.

So do we believe that the Monarks are better than stock? I think it is timing/injectors that are causing my idle smoke. I also get a puff of grey on take off. Not black like wot on #2. Just a grey puff--on both bio and dino and a blend.

Thanks again for input.
