None, maybe the upgrades section needs to be more concise, more possible upgrades.
I own several autocockers, and the timing and tear down have always been something I never wanted to deal with, but in my area there is no one around who tech's them. So I needed to learn to do it myself. These videos really show how easy it can be to time, clean, and assemble the autococker, and Todd does the tear down and up in just a few minutes, and makes it look easy. Great buy for the autococker owner who really wants to know how to take care of thier investment.
