My father-in-law, (now 79 years old) was an old school mechanic. For
years he "pickled" the Chrysler 318 engines in his old Uniflite by
running the engines while very slowly pouring about half a quart of
regular 30 weight engine oil into the carburetor. He would add the oil
very slowly until the exhaust was really smoking and then kill the ignition.

He also did this on car engines that were not going to be used for an
extended period of time.

I think I've told this story before, but the year I was discharged from
the Navy, he roped me into helping him get the boat ready for the
upcoming season. His boat was stored outside at a crowded marina, and
had several boats right around his, including a wooden one with it's bow
about 2 feet from my father-in-law's stern.

We spent the day cleaning and painting the bottom. The owner of the wood
boat behind us was busy painting the hull on his boat a nice bright
white. He finished up, waved goodbye to us and left.

My father-in-law decided it was time to see if the engines would fire
up. They did. He was in the cabin revving them up when I happened to
look towards the stern. You know the rest. It blew all the oil used to
pickle the engines all over the freshly painted hull of boat behind us.

We launched the next day and he moved to a new marina.
