When I got the carb to the store the counter guy said I could have taken it apart if I wanted to and it wouldn't void the warranty. The tech guy from Edelbrock didn't give me that impression but that'll be my course of action if I have an issue again. My thinking too was I just paid 300 bucks for this and I shouldn't have to disassemble and troubleshoot that far.I would like to know what the problem is though.It appears to have been an issue with that particular carb however. The 600 I got works fine after heated up and sitting.
