Tascam 32 Half Track One Motor Going Backwards

Yesterday I took my Tascam 32 out of the closet to run some reels. After threading and set up I pushed the play button, heard it click on, but nothing moved. After taking the reels off and pressing play I noticed that the left reel was spinning in the wrong direction (clockwise).
When I first purchased this deck the capstand thrust clearance needed to be adjusted, which lead to a small screwdriver bit falling into the machine. The machine worked fine, and I couldn't see the bit, so I left it in there.
When I took it out the other day I heard the bit jingle around, but I can't hear it now when I shake the machine. I believe the bit that fell in was magnetic and may have attached itself somewhere in the machine, the only problem is I can't find it for the life of me. Does anyone know if the bit is causing the motor to run in reverse, where it would be? It is possible that this bit isn't the problem, but the machine was working fine when I put it away last. Any help would be much appreciated.

Have had belwell's dilemma a few times while working as a bench tech in the consumer electronics industry; invariably seems that the malefactor (the "hiding" magnetic tool) is in a spot where one would think it just couldn't be! I believe you're likely to find the bit in such a location (inside open-frame motor shields and w/in shaped or formed arms/rods/levers, such as tension assemblies, as well as in the corners of "pockets" formed by a fully-installed enclosures/covers seem to be a favorite haunts) - but I don't think it's likely that's what's causing the inability to move tape. Might I suggest that as a first approach you verify that FF/REW are as inoperative as Play - often I am able to determine what's going on (or NOT going on) by parsing the details found with such a troubleshooting approach...

I might be wrong, but doesn't the supply reel need to have back tension on it (thus the clockwise rotation)?
