Your thought, as I understand it, is that the restriction of the air cleaner caused too rich conditions causing the loss of power. Good thought, but not valid. The engine is not sensitive to how rich the mixture is (as long as you are not pouring clounds of black smoke). The difference in torque for a/f ratio of say 12.5:1 (about right for peak torque) and 11.5:1 (a bit on the rich side) is tiny.
