Does the compound contain ONLY C and H? If so, then convert grams CO2 to moles C and convert grams H2O to moles H (H and not H2).
Then find the ratio of C and H to each other with the smallest number being 1.00.
Frankly, I think you have made an error in posting because if I add g carbon and g hydrogen, I don't end up with 1.367g unknown. So the extra mass could be due to oxygen, nitrogen, sulfur, or some other element. Check your post.
