I6 Cold Start Issue

[Winmon]

Having cold start issues with my 250ci I6 w/a manual choke. Once it is warm, it has no issue starting, starts right up. Funny thing is I can pour a cap full of fuel directly into the carb and it will start right up cold. I then checked to see if the throttle was feeding fuel and it was. It has a clear fuel filter right before it enters the carb so I know the carb is getting fuel. I then assumed the carb just needed to be gone through so I rebuilt it last weekend. Issue still persists. Any ideas what else to check?
