I had our 1850 missing on two cylinders caused by one injector. The one injector was stuck open allowing compression back into the injection pump, so the next firing cylinder got a bunch of air instead of fuel. I would swap out #6 to say #5 so you know the injector before #2 was working good. DOES the engine miss under load or not? If the end of the line is damaged, replace it or blow through it with brake cleaner to make sure it has good flow. These engine are notorious for a high rpm flutter that goes away under load. It doesn't sound like what you're dealing with. Ours did that until we updated the bronze pump drive gear and injection pump drive like on the 2-105's. Another option is to run the engine with the injector out hanging off the injector line an watching the spray of the injector. Are all the camshaft lobes OK or is one worn off? Just a few ideas. Good luck and let us know what you find.

I don't have high rpm flutter, its a noticeable miss / knock on # misses / knocks whether loaded or not. I'm going to pull valve cover tomorrow if I have time and see if the valves are opening like the rest...thanks for all the replies, I appreciate the help and will keep posting.
