Hard starting

All of the above plus no one has suggested that it might be time for starter rebuild. While it might sound like it's cranking the engine over normal it could be drawing too much current. Starters do wear out.
 
Also, make sure the starter switch screws are the proper length. If someone re-tapped the threads in the starter housing too deeply and used screws (actually, slot-head bolts) that are too long, the ends of the bolts will touch the field coil and short out the electrical system = no start until the starter rod is released. I've encountered this problem twice and this was the cause both times. In one of those cases, some knucklehead had twisted one of the incorrect length bolts in so deep that it snapped against the field coil. Using the proper length bolt afterwards left a gap because it couldn't be drawn tight enough to secure the starter switch against the starter casing. A visual inspection revealed the broken shank still remaining in the hole. It had to drilled out. Installing the correct length bolts solved the problem.
This is a long shot, of course, but if all else fails, check it out. If the starter had been acting normally until recently, however, this is not the cause of your problem. But if it's a newly "rebuilt" starter or one acquired from an unknown source, check the length of the mounting bolts and look for a broken bolt shank inside one of the four holes. The correct mounting bolts should be VERY short, almost too short for ease of installation with the starter in place. :)
