Extruder Clogging Issues

I am hoping that someone can help me out here. I just upgraded my hot end to the Creality Ceramic Heating Block. It came with a new Teflon tube that feeds into the extruder. Since upgrading I keep getting clogs in the tube after running the retraction function. I always go in to clean and push any remaining bits out of the hot end before it cools down and I seem to always get clogs up in there now.

I never had this problem with the old hot end and unsure if it is cooling to fast or if I am doing something wrong.

Anyone else run into this or have any ideas?

Thanks
