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 with the
inconel. Also going to make sure the firewall is well caulked.
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.
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.
But, the plane flies nicely, like an RV should.
Next flights will be in a few days.
