Hey 83 z28 with 350. Just did a performer intake with the 1406 edelbrock carb among a lot of other things. Problem lies in I start the car with the choke completely closed and can get it to idle good around 1250-1000 but as soon as i give it some gas the choke will open almost all the way and it will idle around 2500-3000 and rise with every pump. It seems like something is sticking somewhere or my choke is not operating correctly any thoughts.......
