After i was done i went back and checked them all and on some cylinders the .003 slid right in so i did it again and each was good.

You want the .0025 feeler to be tight. I check it by pulling that feeler out and trying to put it back. If I have a little difficulty getting the .0025 back in, it is perfect. The .0025 feeler should have a drag pulling out and a side to side wiggle and push to get back in. You just want to be able to barely get it in there.

I stick the .0025 in there and tighten until it is stuck and just back off enough where it will move, then tighten down. After you get the feel down, you'll start noticing how much you have to turn the slot in the adjuster back after you get to the binding point to reach the proper adjustment. Pay close attention to the slot in the adjuster. Combining feel and watching the slot makes you able to do a set of valves in 5 minutes or less.

What're ya stupid or somethin'!

Just kiddin'. 911 valves are a PITA. Once you get the feel down though, you would never want to do it the conventional way again. You obviously are leaving then loose.

I suppose the only other thing it could be is that your adjusters are banged up and old and never hit the same spot on the elephant foot two times in a row. Doubt it though.
