We dinked around the house doing this and that. There have been a bunch of ants in the critter room, so we've moved the critters out of there and put down powder to kill them. Hopefully. Of course, this means that there's a lot of stuff being move around constantly, and Tilly's been having a ball watching everything moving around constantly.
In the evening we went to the airfield and took the plane out for ~45 minutes. I've been concerned about the cylinder head temperatures I've been seeing, so I set the computer to tell me the individual head temperatures, and and one point one was 80F higher than the other. I'm starting to think it's a problem with the sender, rather than the engine, so I'll look at swapping the sensors - if the "problem" moves to the other cylinder, it's a sensor problem. If not, well... we'll burn that bridge when we get to it.
We were sitting about talking to Sean, the parachute plane pilot, when I got paged for work and had to go home. Stupid work.
