Hey guys,
Here is my setup. 600cfm edelbrock carb, performance cam (unknown, noticeable idle) and headers. Everything else is basically stock. I am having trouble with a very rich mixture. Adjusting the fuel/air screws seems to have no effect. I am also hearing a loud tapping noise coming from my metering rods when the engine is at operating temp. Sometimes I can get that noise to go away while reving the engine a couple times. I am also having trouble starting the car when hot. I takes a couple seconds for the engine to turn over vs starting up immediately when cold. I did take the car to an old mechanic who actually builds race cars thinking he could easily fix the problem. He ended up disconnecting my vacuum advance and plugging the vacuum adv. port on my carb. It seems to run a little better, but the rich mixture and the noisy metering rods have me worried. Has anyone ever had these type of problems or know what could be wrong? Thanks guys.
