It had a little slack, I added a bit more just to be safe

I was under the rig playing today so I decided to adjust the parking brake just to make sure it was ok, since I've read a couple people having them adjusted too tight from the factory. First picture is the parking brake disc & caliper from the passenger side. Second picture is the adjustment bolt. How it works: it's a cable operated disc brake with a locking pawl to hold it where you push the pedal to. Procedure: The pad tightness is adjusted by moving the bolt in the 2nd picture in and out. When you tighten it it pushes the pads together. The extra nut on it is a lock nut. Using a 13mm wrench loosen the lock nut. Back it off about halfway just so it's out of the way. Next tighten the bolt by hand until it stops. From there back it off about a half turn. Push the parking brake and make sure the pedal "locks up" before running out of travel. If it doesn't adjust the bolt slightly tighter and try it again. Once you're happy with the adjustment tighten the lock nut while keeping the bolt stationary.

Is it an overhead valve motor? Sounds like one or more of the valves is stuck open. Or, there's something in one or both of the cylinders. You could remove the heads, or maybe one of those snake cameras would give you some idea.
