We got the plane up in the air again, there was gobs of power, the temps=
 stayed low, no higher than 160 for oil and coolant, but CO in the cockpit=
 reached 300 PPM so it was only one circuit of the traffic pattern and a=
 smooth landing. That SS flex exhaust tube is getting replaced tomorrow wi=
th the inconel. Also going to make sure the firewall is well caulked.=20


 At full throttle the engine is missing a bit, I think it's too rich. The=
 pilot was going to play around with it a bit but due to imminent danger=
 of CO poisoning he decided to land it. I'll take it up on the next flight=
 after some Van's familiarization flights and exhaust refit.=20

I'm using the stock 13BREW O2 sensor, Tracy- is that the one recommended=
 for the EM2? It seems that the EM2 mixture graph shows about 3/4 rich, so=
 I lean it out slooooowly, and it doesn't have a sweet spot- it just goes=
 to about 1/3 scale. There seems to be no in-between.=20

But, the plane flies nicely, like an RV should.=20

Next flights will be in a few days.
