Years ago my buddy that I carpooled to work with called to tell me I had to drive to work that day. He was going to put his car in the shop because it wouldn't crank. I brought my tools and showed up early to see what was the problem. It was an RX-7 with the Wankel engine. I knew next to nothing about it, but it uses fuel and air and spark to go. I figured I would check the plugs, wires, distributor, look for a fuel filter, etc. I took the air cleaner off and tried it. It cranked right up. C'mon man! Learn a little something about cars if you're going to drive an old one. He was so put out with that car he just wanted to be rid of it.
