• Max fuel screw location? by adi on 23 Mar, 2011 14:01
• I've been doing a bit of research on tuning my GTD, and until I get a boost guage and EGT guage I'd like to adjust my max fuel screw as I'm aware they run fairly lean as standard. But I'm not 100% sure which is the idle screw and which is the max fuel screw, theres no plastic collars that I can see. Can someone help me identify them so I can have a play with my fuelling and make it go a bit better?

• The fuel screw is the lower one.
  
  The search is a really handy feature.

• Cheers for that! How many turns and which way is a good start? I haven't yet got a boost guage or EGT guage so this is all I can do right now

• What does LDA stand for?
  
  On the Cummins it is called the AFC, air/fuel control.
