also to add here...when you do drop shims you must be careful not to run it too lean...use the glowplug as your canary in the mine and if you see any distortion in the coils its not happy..either fatten it up, run a cooler plug or add a 0.1 mm back to it....They can run really good this way but have less tolerance for being lean, thats when they will start to detonate....
