I've been tinkering on the car nearly every day for the last week, and I'm not sure I'm getting closer to getting the carbs adjusted properly. I thought I did yesterday before I ran out of gas. After filling it up, I thought I had the carbs running correctly until the battery died. So after charging it and rewiring the alternator, the voltage spiked up to 18 volts, which means voltage regulator either blew out or I've got the alternator wired incorrectly.

Bleah.

I need to wire in an O2 sensor, since tuning by ear is getting old. If I have the O2 sensor wired in, I should be able to know instantly which way to adjust the carbs.
