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.
