So what's the trick for getting seized pistons out. I have my crankcase cover off and was able to get the center 2 pistons out and they are in great shape. The other two I cannot get them out. The piston closest to the generator took the brunt of the water damage. I have it unbolted from the crank but can't seem to get it to move. I soaked it with every kind of penetrating oil, ATF, etc. Seems to be stuck pretty good and is in a bad spot to really get any pressure on it. Just curious if there is a trick or if it is just a brute force process.
