No...pistons are stuck. I've actually got the powerhead off and on the workbench. She be stuck. I have two, so it's no big deal. One is 100% complete and unmolested (and stuck)....the other's missing some stuff but runs nicely and pumps water. I just thought that if I could free it up, I'd disassemble both and use the best internals to make one restoration, and the 'off' the left over parts.
I'll appropriate some acetone at work tomorrow, and replace the Kroil with that.
I say "Pardon Me" a lot. I had a 20H with a toilet bowl, then raced open mod sleds.
