Both of these are probably fine.

I think this is normal. Once you get it running on 4 cylinders, dropping one is 
a 25% loss, while dropping one cylinder out of 3 is a 33% loss.

Idle mixture a bit rich?

If you don't have a thermostat, I THINK it may affect emissions, too. I don't 
expect a cold engine to work as well as one which is warmed up nicely.

Scary prospect!
