New Powerspec Pro User Overhang Question

[R51964]

I am new to 3d Printing (2 weeks) and have purchased the powerspec pro 3d printer from Microcenter. I like the printer overall but I think the wingnuts leave a bit to be desired as they seem to slip and need to be replaced. I am having trouble with overhangs on my prints. I think the bed is level, I feel a bit of tension when passing a piece of paper under the heads. I am running this at a bed temp of 70, but have tried it at 65 and 68 as well. The extrusion temp is 200 but I have run it as low as 190 with similar results. Speed is 90. Resolution is 200 microns. Printed in PLA. Any idea on what I can do to get cleaner prints? Any help or direction would be appreciated.
