On my 307 4 barrel carb making the engine run rough til it opens up. If I take the air cleaner off so I can observe the choke, The vacuum pull off takes too long to open the choke. About 2 minutes of running the choke suddenly opens up and the engine smooths out. I checked all the vacuum hoses are good and go where they should.
