Whats up you guys, I usually whore around the 92+ forum but this is dealing with a 91 hatch.

Im about to buy a 91 hatch for about 2,000 but I was wondering: when I turn it on its fine and everything, it also runs fine, but what I noticed is that when I rev up the car it blows out smoke from the exhaust. Is that smoke because it is running rich or is a gasket or something. Any help is appreciate it.
