Sonow it's just a GT.
anyways when it was still k-jet the issue would have been that the cold aux air device was not working.
So you swopped a system that COULD actually compensate for cold idle for a system that cannot compensate for cold idle. A basic carb that has not got any choke mechanism will always be too lean on cold start and cold idle as a cold engine needs to be richer to run.
Side draught carbs has no auto or manual choke mechanisms so you are back to where you were. Live with it.
