My winter beater '79 has suddenly begun to run very, very rich. To the point where it belches out black smoke, does not idle, and gets perhaps 150KM to a full tank.

Unfortunately, I do not know anything about 1st gen carbs, and I need to drive this car daily while my '86 is in my garage being turbocharged. The car sat for 2 years before I got it, so I assume that therefore something is stuck or gummed up. The strange thing is, it ran fine for about 1.5 months, and then began running rich. I know the carb needs to be rebuilt, which I will do in the summer when I have time to learn about it.

But for now, I need a rather quick solution. Anyone have any ideas? I've tried running cleaner through it, but that didn't really help. If it's a serious issue with the carb, I'll just have to live with it until the summer and fix it then.

Thanks!
