Holley 4150 wet carb base gasket
I rebuilt my holley 650cfm double pumper carburetor (List 4777-5) and after reinstalling it, the engine had a high idle and unresponsive idle adjustment and idle mixture screws. I pulled the carb to verify the transfer slots on the primaries and secondaries were not over exposed and I noticed that the base gasket was wet. I did torque the carb to I think 75 or 80 in lbs per holley's website. The transfer slots looked ok so I am hoping this might be related.
The image shows what the gasket looked like after about 15 minutes of run time. There were no external fuel leaks. What would normally cause this? Warped baseplate?
