It could be stuck further down in it's seat because the spring is weak. But that's highly unlikely. It is impossible for a seal to be stuck any other way than that. There really isn't much else you can do, It could be carbon buildup on one face of the rotor that is causing inconsistent compression as well. To clean that you'll either have to pull apart the engine OR, you can run small amounts of water through specific vac lines . The engine will stumble, suck in some water superheat that water which then cleans carbon off of the rotors.
