Pontiac 400 2801 cam stock quadrajet tune
Car seems to run fine under acceleration however it want to die when pulling up to stop. ( Kinda suspecting the choke) car is warmed up having issues maintaining a good idle I’m running the stock quadrajet carb for 1977 400 4 speed which previously before doing a head gasket worked fine. I smoked the upper half and didn’t see anything that would indicate a leak. I sprayed it with car cleaner and didn’t notice the idol jump or anything. I just had a little bit of a loss. I did notice, however, that the primary air flaps never seen to fully open with the car at 180°. The flaps don’t even appear to have changed from when it was cold.
