Mooney Bravo - normal CO Levels in the Cockpit ? 2 Jahre 2 Monate her #321

Hello,
during the last flight i used a CO Mnitoring device for the first time. I used two different devices, one household-CO-warning device and one professinal unit that continously reports the CO Level in ppm. However, during this IFR Training flight we expierienced CO reading up to 200ppm, 4 times higher that the FAA allowance of 50 ppm. Now i am not quite sure wether those reading are normal on Mooneys, or a sign f a possible smaller exhaust leak. While having the plane checked, i just want to know if somebody has data avaialable. 200ppm seemes way too high to feel comfortable - although this obviously happens when running full rich and low airspeed - typivally initial climbout. The levels could NOT be lowered by shutting off the heater/defroster, and the capin vents in the roof did not improve the situation either. Only opening the air inlets (at pilot /copilots knee position) resulted in immediate relief.
Obviously in cruise and lean cruis climb no CO can form, therefore one could limit the exposure by commencing a lean cruise climb once passing a safe altitude. But usually i climb full power full rich as this keeps my notoriously high CHTs in an acceptable range well below 450 F. I only use cruise climbs during cruise...

Any Comment?

Hello Holger
I can only answer you about my experiences in an Acclaim, so nothing similar in the engine compartment. I use a Pocket Co from KWJ Engineering (Model 300) and the highest readings I have had on it is 5 ppm on the ground during start-up and early taxi. Highest in the air 2ppm with the heater on full power. Your readings sound high.
Hope this helps a bit.
