yeah, dont use kerosene. If it does clean the passages, it will eat the rubber seals in the engine. So, you trade one good thing for a bad one. My uncle used this trick, and it cleared up his clogged pipes, but the rear crank seal started leaking pretty good. He had to have all new seals and gaskets put in the engine. I found that if you substitute a quart of Automatic Transmission Fluid for a quart of regular oil, when you do an oil change, it cleans the engine more passivley, compared to the harshness of kerosene, and it seems to work well.
