Maybe the gear isnt cut right, like one of the grooves not deep enough. Really look the dist gear over and see if its worn abnormally.

Good thought, but I do check this also when I check the cam for bent. This cam only had .001" runout. Most cams I see have .002"-.003" runout and they have never been a problem.
