I must have pushed the bike a quarter mile in the yard and the chain will tighten and slacken as it goes around. I think Jim at Creative Engineering said that sometimes the front sprocket can be the cause. It looks like everything is lined up as good as I can get it. Has anyone else experience this and can recommend a cure, or a source for a replacement sprocket? I guess I am lucky as in spite of the chain I went into the street and was pedaling to start when I looked down and saw that the keeper on the master link was gone and the link was beginning to back out. I put everything back up and hope to get to Tractor Supply in a nearby town tomorrow for a #41 chain, tensioner, and spring.
All tips and help much appreciated.

Your problems with your chain tightening and slackening while you rotate
your rear wheel is simply a very common problem of chain stretching. This happens when the TOP HALF of the chain is jolted by a hard start or from
popping wheelies on motorcycles. I've seen the best of chains get stretched on just half the chain hundreds of times during my 20 plus years in a motorcycle shop. You must replace the chain, there is NO adjustment to remedy that problem!
Change is inevitable and progress is OPTIONAL!
