When I was a kid 13-15 my buddy bought and old snowmobile a arctic cat 440 panther I think. Middle of the summer engine was froze. So we pull the heads and took a claw hammer to the pistons. No lube no block of wood just pounding on the piston. It worked freed it up then we started it and ran it around his lawn. Lol makes me cringe thinking about it. Lol

We had an old Sno-Jet that froze up 2 summers in as row. Some ATF poured in and wait. 2 days later give a pull and it's free. About 300 pulls and lots of smoke later I was riding!

Needless to say, but be careful with the open flames near the acetone. Highly flammable.

One of the guys on the boat forum was using a kitchen mixer to stir epoxy. He later cleaned it in acetone.

Accidentally switched the egg beater on and insta-fire in the boat. Luckily he had a fire extinguisher nearby.

That'll ruin your whole day right there.

you can mix it up in a coke bottle, then punch a hole in the top works great. I also use a cke bottle with mix in it to squirt in carbs to crank em , well I really use Dr Pepper bottles lol I don't drink coke

I buy WD-40 and Kroil by the gallon .I have tried tranny fluid and acetone with partial success .Always have a can full of kerosene or diesel fuel sitting around .Even have some aerosols of PB Blaster .They all work .They claim Coca Cola works but I've never tried it .Citrus oil does work on rust .How it works on aluminum oxide I have no idea .
What's surprising about things is unless the engine was under water in the Atlantic ocean for a decade usually the damage to the cylinder and piston is minimal .More often than not they are salvageable .

Years ago I used Coca Cola to free a piston and it worked well.

Don’t remember if it was diet or not.

funny Al...my "mix recipe" is 1/3 acetone 1/3 ATF 1/3 diesel and 2x the "patience"...time is the key to a "loosener"

Coca-Cola works on rust simply because it contains phosphoric acid; which is also the active ingredient in 'naval jelly'.

Watch the video tree monkey put up. That 036 piston came right out!

Kroil and gun solvent works for lifting crud, copper wash, lead from barrels.

A solvent gets into/under crud while carrying some kroil/ATF with it.
The Kroil is a surfactant, it floats the crud helping it to release from the part/barrel/cylinder.

Get a little surfactant/lube into and under the crud so when you whack the offending part with a hammer it moves .

My favorite stuck engine story is my old Ford F-250 that was brand new in 1977 ,I was brand new in 1948 .It was stuck so I drowned the cylinders with Kroil and let it sit for a week. Then I broke it loose with a grease gun filled with motor oil .I couldn't get it to roll all the way over so I bumped it with the starter and got drowned with oil from all 6 spark plugs being out .Fired it and drove it out of the woods when my wife ran screaming out the back door"the trucks on fire ".It blew all that oil into the exhaust system and was smoking so bad you couldn't see the back of the truck .Looked like something from an Alfred Hitchcock movie .
