[Vwdiesel] speratic knocking - details inside

[LBaird119 at aol.com]

  First:  IT'S NOT A CHOKE!!  ;-)  It's a timing advance.  Regardless of 
where you set the timing, it WILL advance when pulled.  It advances 
timing relative to itself as it has no clue what it's timed to on the 
engine.  If you hear no difference (when cold mostly) then it's either 
far too advanced or retarded.  Not that it isn't making a difference, you 
just can't hear it. 
  My first thought is something got in an injector and it's pissing a 
stream rather than a fine mist.  A cylinder will knock much harder 
with a bad injecor.
