Thanks for the update. I'll follow your suggestion when I receive the part.
I, too, have found the snails a pain in the arse. I use needle-nose lock pliers when adjusting and never get it right on the first try. All this while resting on my elbows, laying prone alongside my bike in the driveway.
BTW, I have learned to prop up my back wheel off the ground with an 11 x 2 PVC pipe. It works so well I carry one on the Revival, as a case for my folding air pump.
