I started back working on my '86 CGT. I got the new starter, distributor, and it is now running, but very bad. I had a small electrical problem today, I don't know why but the battery light came on and then it started to smoke, now I have no gauges, but the battery is brand new. Also, the only other thing that I know of that needs to be changed is the doughnut on the exhaust manifold is non existent, would this make it run terribly?
