PLA sticking to nozzle

I finally have time to work on my Taz again, its been down for some time with a printing problem. The PLA tends to stick to the nozzle rather than the print bed. I had thought the nozzle was clogged and replaced it, but it seems to have the same results. I’ve tried temperatures between 180 and 195 and I’ve tried bed temps from 50 to 60. Doesn’t make much difference. I’ve leveled the bed multiple times with no change. Any suggestions?

Here’s a picture of a typical print

The print head is from a Taz 5, with the other necessary upgrades, the rest, including the bed, is a Taz 4.
