Using pulseIn with analogWrite

It seems that analogWrite does not work when being used with pulseIn.

Here is some simple code:

void loop()
{
  int pulse = pulseIn(3,100);
  pulse -= 1020;
  if(pulse < 0)
    pulse = 0;
    pulse = 420 - pulse;
    pulse *= 0.607;
    Serial.println(pulse);
    analogWrite(13,pulse);
}

The value of pulse is verified to be 0-255 by printing out the value, but the LED on pin 13 doesnt get dimmer/brighter, it only turns on or off at mid range. Any ideas?
