Finder repeatedly beachballs in Mavericks on 2009 iMac.

Question

I have a 3.06 GHz Core 2 Duo iMac with 8gb ram running Mavericks. In both 10.9.2 and 10.9.4 it will beachball for 15-30 seconds every time I try to do anything in finder. Force Quit Applications will show Finder (not responding) while this is happening. It will always end up working after the 15-30 seconds but doing ANYTHING in finder causes this (opening a folder, clicking on desktop, clicking on an external disk).
At first I thought this was my hard drive going bad so I replaced the hard drive and restored my software from a Time Machine backup. Still had the same problem. My next step was to wipe the hard drive and re-install mavericks and no other programs. The problem still happened. I've tried repairing permissions and doing repair disk. At this point I updated from 10.9.2 to 10.9.4 and still have the same problem.
My drive has a small second partition on it running 10.6.8. Booting into Snow Leopard = NO FINDER PROBLEMS!! which makes me think this is not a hardware issue. Any ideas?
Console doesn't seems to have error messages that coincide with the beachballs. Also, I can access and use any program besides finder while it's beachballing with no issues (for instance typing this in chrome while finder locks up).

Launch the Console application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Console in the icon grid.
The title of the Console window should be All Messages. If it isn't, select
          SYSTEM LOG QUERIES ▹ All Messages
from the log list on the left. If you don't see that list, select
          View ▹ Show Log List
from the menu bar at the top of the screen.Click the Clear Display icon in the toolbar. Then try the action that you're having trouble with again. Select any messages that appear in the Console window. Copy them to the Clipboard by pressing the key combination command-C. Paste into a reply to this message by pressing command-V.
