You may want to do a compression check. If you don't have a compression tester, you can get one fairly inexpensively at places like Amazon.

Do the check once with cylinders dry, then add a teaspoon of oil to each cylinder before you check again. If any cylinder shows significant improvement, that is the cylinder with ring/piston/cylinder wall problems.

If you have a bad cylinder and compression does not improve with oil then there is probably a valve problem.
