Had a jack that started getting very inconsistent, tried the bucking, barrel, hopup to no avail. Serviced the Jack and swapped all the O-rings, good as new. Keep a few sets on hand, they're cheap.

Great quality as always from p*, I didn’t realize they started including the screw at the bottom of the engine which is nice its included. I suppose I can disregard the warning on the manual stating to not remove
