Has anyone ever heard of doing a "ring job" by dumping Bon Ami down the carburator? A couple of old timers told me about this 20 years ago and I've never tried it. At the time, I had an old garden tiller that burned large amounts of oil, (it was an old tiller from the late '60's, early 70's). I was complaining about this one day when one of them told me to crank it up, run it at high idle and pour Bon Ami down the carb. They said this would "re-seat" the rings and break the glaze on the cylinder walls. After this "treatment," I would have to changing the oil, but it would stop the oil burning, (or at least slow it down). I never did do it as that season the motor threw a rod. Just wondering if anyone else has ever heard of this and tried it.
