Title: Max fuel screw location?
Post by: adi on March 23, 2011, 02:01:27 pm

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.
