I've measured CO as high as 38 ppm and the odor is strong. The good news is that this concentration gradually decreases to 1 or 2 ppm CO after transitioning to level flight. My Mark II is constructed in accordance with the plans. I'll be doing some more source investigation but it appears that the exhaust is entering in thru the flap control tube opening in the fuselage wing fairing that abuts the inboard end of the flap. My exhaust system is the Style III stainless steel crossover from Lancair (Snowline Mfg.) that exits near the left side of the cooling air outlet in the bottom of the cowling. If any one out there has experienced a similar problem and found a fix I'd sure like to know about it. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> LML website: http://www.olsusa.com/Users/Mkaye/maillist.html LML Builders' Bookstore: http://www.buildersbooks.com/lancair Please send your photos and drawings to marvkaye@olsusa.com. >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>
