You will have to get your hands dirty and inspect your engine to determine problem. If your starter spins without spinning engine, there's several possibilities.
If it makes screeching/scratching noise
1. starter clutch slipping see Greg737's post below. Remove flywheel and spin starter-clutch by hand. It should grip tightly in one direction and not in other. Remove starter-clutch and inspect ring-gear hub for scratches, showing slippage.
If starter spins freely without screeching/scratching noise
2. sheared teeth on starter. Remove starter and inspect teeth on shaft. Manually spin starter by powering it with jumper cables, does it spin? If so, starter is most likely OK.
3. sheared teeth on ring-gear. Remove left side alternator cover. Spin engine by hand and inspect ring-gear making sure all teeth are present. I had hydrolocked engine due to leaking petcock and carbs filling engine with petrol. Trying to spin starter in that situation resulted in 4 broken teeth on ring-gear. I fixed it by welding teeth back on.
4. sheared ring-gear centre. Try spinning ring-gear by hand. If it moves easily by itself without spinning engine, then weld at centre hub is broken. Remove flywheel and starter to pull out pieces. Get replacement ring-gear or weld it back together.
