What kind of carb adjustment
It seems to be working. I pulled the choke cables and inspected them. At the valve end there was a mismash of springs were one-each was expected. On one side 2 small springs were intertwined. On the other side, again 2 springs but one was much longer and actually fit over the whole value. I lubed the cables, worked out a matched set of springs, installed and adjusted them. It's still tight but seems to have an effect.
I don't know if it mattered but I replaced the battery too. Remember, it started with a squirt of starter fluid so I don't think the battery was solely responsible. I think it was all a choke problem.
Funny new problem. The tank and seat have been off so long it seems like they don't fit anymore! Actually, I think something's sitting too high to allow the tank's side bolts to align. Everything looks tight and low but the tank sure won't line up. Oh well!
