Flooded Engine Sputtering Side Pipes
This is my first time driving an older car in a long, long time. I have a 1969 427 that I just had factory side pipes put on. I just picked her up from the mechanic. She started fine drove fine and I got into my driveway fine. To get up into my garage I had to keep giving her gas while I was reversing. I think I might’ve flooded the engine. I shut the car off and the side pipes continued to spotter for 2 to 3 seconds. I got nervous and tried to start it again and it wouldn’t turn over. I had to fully depressed the gas pedal and then it finally started. I drove it around for about 10 to 15 minutes, backed again into the garage, but didn’t give it quite as much gas and when I went to shut it off again, the side pipes sputtered. Is this normal?
