Most likely a worn bendix. What happens is when the engine first fires it sometimes violently spins the pinion gear which sends the pinion back down the bendix screw until it slams into it's "home" position. And if the bendix threads are worn the pinion may jam when it hits the bottom of the bendix screw. Then the next time you try to start the pinion will not screw out until you manually unjam it with your screwdriver.

Sometimes a little more life can be coaxed out of a bendix by putting a bead of weld to form a new stopjust above the point where the pinion "bottoms out" on the screw . However for about $40 or so you can buy a new bendix assembly and solve the problem permanently.
