i have a yanmar 3TNV 80FSDSA in a post driver. the engine is rated at 23 HP and i am sure it is under fueled to meet emissions. does anyone here know how to adjust the fuel up just a bit on these engines?

I have the same size Yanmar diesel but being 25 years old, I'm betting everything is different. If you think it may help, I can check the workshop/service manual for you.
Have you checked places like Youtube? I found this video but it's not the exact same engine you referenced.
