Get #1 on compression stroke with crank set-screw down (6 o'clock) . Adjust #1 to .015 . 1/2 turn , set screw up (12 o'clock) Adjust #2 to .015 . Another 1/2 turn adjust #4 . One last 1/2 turn and adjust #3 . If I'm reading my notes right this is the right procedure . Can anyone please verify this ? THANKS !!

1-2-4-3... every 180 degrees... sounds like a plan.
