we use to dribble bon ami, down carb on radial aircraft engines to help rings seat . it was bit smokey, lol. it was used as a last resort before engine was torn down. it would deglaze the bores?

For the guys who used top engine cleaner. Have you ever tried Ice Water? Basically do everything the same as top engine cleaner. Except use ice water.

I idon't know about ice water but I have seen guys crack the throttle open and shoot a garden hose down the carb. A little pre-teardown steam cleaning I guess.
