I recently picked up a 2F short block. When turning the crank by hand, there is what I will call resistance, in other words it hits a point in the cycle where it wants to stop (not rotate freely) and I have to apply more pressure in order to fight past the resistance and continue the cycle. This happens when cylinders 3 & 4 are about 2/3 the way into their up stroke. I can push them through the resistance and to the top of their stroke. Then, as they start to go back down, the resistance is present once more, where it is slightly harder (but not difficult) to get past, before returning to smooth, for the remaining cycle until I get back around...
Any thoughts? My assumption is something in the bottom end, bearings, etc.
Thanks,
