Oh wait... scratch that... you said PWM but you probably meant GPIO ports. (I just remembered PWMs are output ports only.) GPIOs have 5V continuously available. So you should have 5V present and they have internal 5V pull up resistors, so the signal should be clean.
Unless you damaged the encoder wheel installing it, this suspiciously looks like a software glitch. Still before doing any software stuff, you really need to look at the "signal in" levels with an o'scope or in a pinch a multimeter will work ( just to prove you get level changes).
I need to read these posts with greater care.
