Pistons froze up....whoopie

I did everything I was told:

1. I soaked them with Kerosene and brakefluid.
2. I soaked them in "Tranny" fluid.
3. I put diesel fuel in the holes and set them on fire...and
stil stuck...wound not budge when rocked a little with a big pipe wrench on the crank.

TheN, the thought occurred to me, they did not have aluminum pistons in 1927 so

I cleaned all the oil and stuff out of the holes and filled the holes level full with Muratic Acid.

and then went and played with my grandchildren for 2 hours.

When I got back, I took the pipe wrench to the crank and rocked it...it moved! and Moved! and was free... Whoopie!! All of the rust was eaten from the sidewalls and the top of the piston...slick.

I dipped the acid out. Soaked the balance up with rags and then poured in a solution of baking soda and water to neutralize the acid. Then, flushed all of that out with water...then put motor oil in the holes and rotated it through several times...

I AM GOOD TO GO TO THE NEXT STEP!

The acid will take all the rust off iron, steel and cast AND it will take every bit of the oils out of the metal...the result will be almost instant rust...even though you neutralize the acid. YOU MUST IMMEDIATELY THROW THE PART IN A TUB OF OIL AND LET IT SOAK TO GET OILS BACK IN THE PIECE or clean it further with lacquer cleaner and immediatly prime it getting it ready for paint. I clean all of my rusty nuts and bolts this way.
