John,

Now that you know how to run diesels, give the DEEZIL a chance. I would check the needle assembly to see that the spraybar hole does not have burrs and is oriented correctly, and that the needle is properly tapered and not bent or off-center.

Also make sure it is completely broken-in using short/peak runs followed by complete cool-down to provide proper iron/steel heat cycles. Since it is a long stroke engine, the large props you used are a good size.

I have not had problems with my compression adjustment. My experience has been that most long stroke diesels are not too sensitive on compression adjustment.
