I've got an aging, rich running, oil burning, fleet of small engines . . . mower, tiller, snow blower, etc. that carbons up plugs in a hurry. Scraping them isn't really effective. Grit blasting leaves them rough and full of, well, grit. Pyrolizing the carbon with a propane torch or in a self-cleaning oven works well but seems a bit drastic.
Is there some sort of chemical, perhaps a lye solution, that would take off the carbon without harming the plugs? It seems a shame to throw them away after only a few actual hours of use.
