Rotary encoder without interrupts

[Workinonit]

I am attempting to implement a rotary encoder the way that I have done before with an Arduino many times without any luck. It only ever reads nothing or just down... I am using another library that is very interrupt inclusive and I cannot use interrupts, so trying to debounce without interrupts... I have changed the counter up and down but not had any luck. This runs perfectly acceptable on a Arduino Pro328. Any help is much appreciated... Code follows...

As always...

un

signed long delayt = 1000;
static uint8_t counter = 0;      //this variable will be changed by encoder input
static uint8_t tmpcounter = 0;      //this variable will be changed by encoder input
int8_t tmpdata;

//encoder definitions 
#define ENC_E 6  // pin 6
#define ENC_F 7  // pin 7
#define ENC_PORTB PIND



void setup() {
Serial.begin(115200);
  pinMode(ENC_E, INPUT);
  digitalWrite(ENC_E, HIGH);
  pinMode(ENC_F, INPUT);
  digitalWrite(ENC_F, HIGH);
}

void loop() { 
  tmpdata = read_encoder();
  if( tmpdata ) {
    if(tmpcounter%4==0) {
      Serial.print("rotary = ");
      Serial.print(tmpdata, DEC);
      Serial.print("  -  ");
      delayt+=tmpdata*50;
    }
    Serial.println(delayt,DEC);
    tmpcounter += tmpdata;
  }
 }

/* returns change in encoder state (-1,0,1) */

  static int8_t enc_states[] = {0,-1,1,0,1,0,0,-1,-1,0,0,1,0,1,-1,0};

  old_AB3=old_AB;

  return ( enc_states[( old_AB3 & 0x0f )]);
