Hey y’all, my first post so I’m new here. Bare with me, as my mechanical experience is slim, to none. Anyway here’s what happened to me tonight cruised my 54’ bel air about 20 miles on the freeway to a nearby cruise night tonight. As I was taking the exit for my stop I let off the gas and coasted downhill to a stop. After about 5-10 seconds of letting my foot off the gas and I a large loud backfire, and then a second a few seconds later. While coming close to a slow roll at this point as I was getting closer to my stop it died off. Let it sit a second and fired it back up, made it about a mile from there to my destination and it died off again while I was “slow rolling” into the parking lot. It ran OK around town after that, and then when getting on the freeway to come home it started bucking as I was picking up speed, and finally smoothed out. Ran the 20 miles home ok again, and then died at a red light just before my house. Fired back up and drove the few blocks home. A buddy of mine said it sounds like it leaning out, could be the carb float or needle. I’ve frequented the forum here and silently gained knowledge from y’all, so I figured I’d try my luck here. Any ideas is greatly appreciated!
