For engines that had set up and started to stick, we used to get them started
and feed a quart of automatic transmission fluid through the carb, keeping the
revs at about 2000 so that the engine doesn't die. Then we would leave it
alone for about an hour or two, fire it back up and put it on the street.
Try it, maybe it will work.

This is an old trick for burning carbon deposits off of combustion
chambers, pistons, valves, ports, etc. and may work quite well for stuck
rings, BUT please bear in mind that it can clog catalytic convertors
permanently...caution is warranted on 1975+ cars...

was developed to clean carbon from electric motor commutators, and will
to a good job of de-carboning engines. Just raise the idle and trickle it
in. It will pretty well trash the plugs though.

I think that what happens mostly, when an engine sits up until it starts to
stick, is that gas and oil residue in the cylinders and valve stems and other
assorted places turns to a crude varnish and this is why ATF (very detergent)
works so well. It disolves the varnish. Also, usually slight rust forms and
the oil in ATF helps lubricate the rough spots. I don't think we are talking
primarily about carbon fouling keeping the engine stiff. Although, if it is
carbon that you want to remove from the combustion chambers, water works real
good, as does a few other things. Some folks also recommend running a little
diesel in the gas tank to clean carbon out of the chambers, it works but you
can cook your engine real easy doing this. A friend of mine ruined his '56
Pontiac doing this. Never tried it myself...
You pays your money and you takes your pick..... and sometimes you win!

Try a quart of ATF in the crankcase. Drive ~ 100 miles and then change
the oil. Do this a couple of times. I have had good luck with this for
loosening up the rings. I have heard that Marvel Mystery oil works, too,
but have not tried it myself.

This is also used to clean injectors, as described by a local dealer
mechanic to achieve the same result as the expensive 'shop'job many pay
for.
