Hot damn fellas. Put a tach in and started to figuring things out timing and carb settings. Actually the Tach I wanted to add to determine when the transmission was shifting. To me it seemed really early. BUT since I had a reliable way to see RPM I took the opportunity to tune a little bit. I can get 22 inches of vacuum at 650rpm but boy does she ping like hell off of idle. Went back and set the advance to the book 12.5 BTC, set the mixture screws to max vacuum and only managed 17". But from a dead punch she'll make the tires cry a little bit. Rolling about 40mph and kick her down, big smile on my face.
So to the initial issue I wanted to address, it still seems like it's coming out of first too quick. I expect 2500-2800, and it's shifting to second at about 1800. To me even at light throttle that's too early. I'm second guessing the need for a rebuild because it seems to do really well for right now. We'll see.
Right now though, happy happy happy.
