All right, first I know how to use the search function but after searching the everything diesel forum for "tuning" I have come up short after 5 hours of reading. If you look for how to tune a glow engine you will find 100 ways of doing it. I have found almost nothing that describes in detail on how to tune a diesel engine. Most threads are just talking about when you figure it out it will be easy, well I need some instructions on how to figure it out.

Is there a thread or link someone can point me in the right direction? The things I have figured out is you can either increase or decrease compression to start the engine. You turn the comp screw in or out after the engine starts. And you richen or lean the carb to get it to sound right. Now that is a bit confusing because you have a 50 - 50 % chance to get anything right.

Lets say I have just attached a conversion head to the engine and have the comp. screw all the way out. I have primed the engine and flipped the prop and keep increasing comp until it pops and starts for a second on the prime. Where do I go from here?

Thanks for any help that can be offered.
