I finally started my 67 and I have an issue that I think is a vacuum leak but I wanted to see if anyone else had any ideas. It is a rebuilt 390, new comp cap, new Pertronix distributer, new Quick Fuel Carb and Edelbrock intake.
When it starts it takes a little feathering to keep it going and if you give it gas it boggs down and sputters. . After a few minutes the idle increases to 2000 RPM but the accelerator has not moved and the butter flys is not open. Nothing really makes it slow back down but eventually does. It never really smooths out and becomes responsive.
I do not have power brakes and it is a 4 speed car. I have checked the vacuum ports on the carb and changed the gasket between the intake and spacer and the spacer to the carb. I am thinking it is a vacuum leak on the intake.
Any thoughts would be appreciated.
Thank you,
Jackson
