The manufacturer's repair manual for the Miller Big Blue 400D CC Duetz F3L2011 engine is known as the "Miller Big Blue 400D CC/CV Diesel Engine Driven Welding Generator Service Manual" (part number: 907596). It provides detailed information on troubleshooting, repair, and maintenance procedures for the engine and welding generator.
This manual can be obtained from Miller Electric or an authorized Miller distributor. It can also be found on the Miller website, you can download it from there.
It's important to refer to this manual for specific instructions and guidelines for troubleshooting, repairing, and maintaining your Miller Big Blue 400D CC Duetz F3L2011 engine.
Please note that this manual is for the Engine, you should have a separate manual for the welding generator itself, it's important to refer to the manual for the welding generator for specific instructions and guidelines for troubleshooting, repairing, and maintaining your Miller Big Blue 400D CC welding generator.

Nowhere, Service manuals are several hundred pages. If you own the engine then you need to purchase the manual.

The problem is not so major. There are a couple of things you need to check.

1. Make sure you are not getting dirt in the system because it will cause the "needle and seat" to not seal properly when the float chambers are full.
2. Reset the float level. In time the "needle and seat" in the carbs wears and consequently you will need to reset the float level. You can contact me if you cannot find the float specs and I'll tell you how to do it without elaborate measuring equipment. It's sort of complicated to explain but easy to do.
3. Worse case scenario you will need to replace the "needle and seats" in the carbs. They come as a unit sold separately so you will need one for each carb.
4. You do NOT need to replace the carbs. DO NOT go buy a new set, you're wasting money. The fix is really quite simple and at a fraction of the cost if any.
   

My experience tells me that you should almost be able to simply readjust the float level to cure the problem. The needle and seat will endure up to 12.5 lbs of fuel pressure minimum so not to worry.
Best of luck and let me know if you need further assistance.
