Having the valves adjusted too tight will kill compression.
You can see if it's the rings by putting about a teaspoon of oil into the spark plug hole and test compression again. If rings are bad, the oil will temporarily seal them and increase compression. I agree with the others though; it should burn oil like crazy if the rings were that bad.
