More progress.
If a car goes for 1 mile, it will probably go for 10

I put in a nice 40 mile drive today, so should be good for 400. That won't quite get me to PUB 2015, but is a good start.
I still have some mixture problems, in particular at light load around 2000 rpm it's running really lean with an AFR of 150-16. Under heavy load it's fine. It also doesn't down shift from 4 to 3 under load. Gotta pause fro a few days to tend to other projects, but should be back on the case mid next week.
