On my C Code I have replaced the fuel pump, fuel lines, fuel filter and carb. All are Edelbrock components. Here's the issue. When I got the car running it idles really well. When I rev the engine it dies out when it idles down. Then it is very hard to restart the car. Thoughts? I spoke to Edelbrock and they said I need to adust the idle on the carb. Is is really that easy? Seems like there might be something else going on.
