How do I go about checking the head for detonation? What am I looking for?
Look at the glowplug after each run. Make sure that it does not look dry. The bottom of the plug should look shiny, or glossy. If it looks flat, or dry that is too lean, and could cause detonation if you continue to run at that setting, or go any leaner. If the plug looks wet, then you have more room to lean the engine. This is the best way to tell if you are running optimally, not the temp gun.
