sam83-johnboy-I use the johnboy method also-start at the valve.The trick is to not insert the valve all the way initially,so you can get the bead as deep as possible-well under the valve.Works for me;once you start to pump it up the bead will lift into the groove-hook,and the stem can be full seated.
I initially pump up to 20 lbs-then bounce the rim around a bit to make sure it is seated,and to check the stem angle(90 degrees of course).I then deflate almost completely and pump it up slowly to 40-bounce-50 bounce etc.Luck,Charlie
