h 2 o injection
I too have wondered that, but moreso about making my own kit. Also, you hear of folks pouring water down the carb throat at high speed to clean the carbon out of the motor. So, I took a plastic irrigation solution bottle (hospital item, 2 liters), and filled it with water and a little rubbing alcohol, put a small diameter tube into the container and the other end onto the vacuum advance nipple of the carb. This was on full centrifugal advance ditributor setup, and drove around that way. Did'nt seem to hurt anything, can't say it helped, but I reasonned that the engine would pull more vacuum under load, and therefore more water ,to stave off detonation. Could one "tune" it with some sort of jetting, and would that work?
