Drive tune round 2: upped the secondary jets from 66 to 71. Wasn't going to start with that much initially, but I only have 1 each of 69 and 70 jets, so that's how that happened.....
Got out on a relatively empty straight away, slowed down to about 30 in 3rd gear and let it eat. Still seems to be a tad lean, kept in the 15s until I let off around 80mph. So I slowed down and tried it again with the same results.
As I was returning home I noticed my temperature gauge started rising. My initial thought was the fan connection as it was a tad loose when I was putting the manifold back together. I thought I had tightened it, but maybe it come undone? So I pulled over, temps still climbing, popped the hood and checked. It was still connected and the fan was blowing, but I was dumping coolant from the overflow. Since I was only about 2 miles from home I jumped back in and raced home. So now I have to investigate my cooling system again. It was fine last night on my initial drive in the dark, fine today on my first run, now it's puking coolant?!? Talk about pissing a guy off.....
