Long around 96 or 97 I was using a 66 Mustang as a daily driver and I'd just gotten off work and it was about 1:15 in the morning. I drive about 9 miles on I-44 to and from work and when I got to my exit and slowed down to stop for the light the Mustang died. It had been running pretty crappy the last few miles and I got it stared again but it died shortly thereafter. Since it was in the summer I had the windows rolled down and I smelled gas. I got the car off to the side of the exit and popped the hood and the front bowl of the 650 dp was leaking like a sieve. I always carried a small tool box in the trunk so I tore the carb down and replaced the o ring on the needle and seat. I was fortunate to have a spare and when I got it home I replaced the one I used and it was a good thing because a week later I had to do the same thing for the rear bowl in the parking lot at work. The gasahol I'd run it a couple of years earlier was the culprit.
