Chinese fella and all - thanx for the responce. When the unit was in OH it had a new nozzle fitted, I agree with you though - for what ever reason things do change in the field hence we are where we are at! I hear ya they soon came out with the 30P right !
I guess we try shimming again or like you said have another nozzle to try it out, the red herring seems very likely as they did not want the unit back under warranty and just gave us this great excuse -
Bug driver - Its ma good self, need to change location from De Bahamas mate, having fun yet?
