Pulling down a 77 with some very stuck pistons. They are up near the top of the stroke. turning the crank is moving the cylinder up and down about 3/8" (10mm finger boy)
rust buster sprayed on a couple of times. solid hits on a hardwood block then some smacking with a brass mallet. nothing yet.
I have some more irons in the fire, but hey maybe someone has a neat trick I haven't heard.
I will just toss the pistons but hope to keep rods and cylinder in good (rebore) condition.
pics in next post.
Engine looks good inside otherwise.... so far. Valve ends, adjusters, no dimples or chips. Engine was in a group parts buy, someone gas wrenched the top of the frame off cutting through the mounts just to get the cam out, then threw the engine back together.
