For the first time since owning my '77 I am experiencing a rough running engine. It has been idle for several months except for the occasional warm-up. We went to Navarro Mills Lake in the Liberty Hills camp for a week for our Thanksgiving with all the kids(about 90 miles each way). On the way I began to think I had lost some rubber off a tire because of the vibration. Can a rough engine give that sort of vibration? I pulled over to inspect the tires, but found no problem with the tires. However the engine was missing very badly. Can a rough engine give that sort of vibration? Also smelled of unburned gasoline. When I continued I reved the engine thru the gears a couple of times and it seemed to smooth out somewhat. But if I let it idle for very long the roughness returns. On the way home I believe it was a little smoother. I also think the gas guage went down too fast. I'm of the impression the carb is the problem. Any ideas?
