Question for Tractor Vet

I've read on here you knew how much to turn your torque stop screw for stock, +10% and +30% on your 450D. My SMD had the pump set up for +8% and I was wondering if you could give me an idea of how far I need to turn it in for stock fuel delivery. I was thinking of giving it one full turn in but thought you may have a better idea. I don't need all the smoke anymore and was told it may be stressing the head more than stock combustion pressures would.

Thanks,
Dan

The main thing that stress the head is not allowing the engine to warm up before using it and not allowing it to cool down long enough before shutting down . And always shut down on the diesel side . Switching back to gas only heats the head back up. Now as to how much to twist the screw do it a half turn at a time till ya feel your comfortable with the set . When i had my 450 D i had put center punch marks on the threads for several different settings and this was done while the pump was on the pump stand . I ran mine at around 75-80 Hp. for farming and for the pulls it was backed way out . Yea she did smoke while plowing as one neighbor said he knew how many rounds we had made in the field on a still day by the rings of smoke hanging in the air.
