Sounds like the chain has been set too tight and so when you hit a bump and the swing arm moves up the chain runs out of slack and stretches the chain giving tight spots.

If the sprockets are in good condition just change the chain.

Whatever happens, slacken the chain a bit more as you could damage the shaft and bearing that the front sprocket fits onto as wel as the rear wheel bearings.

Poor lubrication over a long period can also give tight spots as wear occurs more in one place than another.

Get your local bike shop to check out the chain, sprockets etc if your in doubt.

Old chains end up with tight spots, this would explain the tightening as you turn the wheel, remember the chain should be adjusted to have up and down play WHEN YOU ARE SITTING ON THE BIKE, if you adjust it to give play without you on it, when you do sit on the bike the chain will be like a bowstring, then hit a bump and it will get even tighter, this can really damage the front sprocket bearing, I would clean and lube the chain if its not over streached (how much adjustment have you got left), re set at the correct tension, I give it about an inch of play when you are on the bike, and see how the wheel spins, if it is ok then fine, if not new chain and if required sprockets and if the noise is still there, fit a new sprocket bearing, there is a thread on how to do this on here somewhere, the auther did say it was a simple job, hope this helps and also hope I have not told gran how to suck eggs, DD.
