I cleaned up the large ring and took a close look at it and it does not appear to have any problems. I did notice that the teeth are lower by design at some points around the ring. Both the small and medium ring also have these lower teeth at the same locations.

I checked the wear on the chain and it is about 3/32" longer over a 12" section. The chain also had a very little tendancy to want to stay on the large chain ring when I back pedaled the crank by hand. The bike is an 8 speed and the chain line on the large ring seems to line up with 6 th gear or maybe 7th gear. The bike was trying to shift when it was in 5 th gear. I didn't test the shifting in 6th 7th, or 8th gear. I am thinking that the top 3 gears work perfectly.

It looks like I need to change the chain due to elongation. Is there much of a chance that this will fix the problem?
