My 14.2 mod 3 comes, as most do, with a tiller extension with no labels other than "Tacki-mac" on the end of the rubber handle grip (Note: strangely enough, Googling this grip, I get hits associated with golf grips and hockey!). My question has to do with the u-joint which is two stainless steel yokes held together with a large-cap phillips head screw that seems to be welded in place. It has metal-to-metal contact, with no washers. The joint it seems loose enough, but doesn't swivel as freely as I expect it should. Do your tiller extensions feel a bit sloppy (very loose u-joint), or do they catch in certain parts of the rotation, and/or do they feel free to rotate through all angles? Do you lubricate the u-joint? I'm thinking of cleaning it with WD-40, then using Boeshield T-9 (just great stuff).
