I could not get my car started a day after a race. I did not think I was getting a spark. I had the ignition box checked and it was ok. I then put it back in car and there was a spark. still would not start. we spray some starting fluid in it and it ran for a second. Did it again an it would run until the starting fluid was gone then stop. we check for clogged fuel lines to the carbs. Then pulled the carbs(zenith stromberg carbs) off and took them apart and cleaned. We did not see anything wrong or any dirt... that would not allow fuel to the engine. Everything seemed clean and open. Put the carbs back on and shot a little starting fluid and it run then shot a little more fuild to keep it running and then it finaly ran and was able to take fuel and run normal and idle. Turned the car off and restarted it a few minutes later and ran fine. I will see what happens in a few days. I know it was a fuel problem but what and why did it fix itself. Any thoughts or ideas?
