Keith,
Just did mine last weekend, the measurement was the same on both of mine. But that didn't help me, when I was done the idle was about 150rpm's too high. I ended up re-adjusting mine 3 times to get the idle right. Screwing the adjuster tighter will increase idle, loosen will lower rpm's. My spring was set right by adjusting the screw down till I felt 1 soft click, then turning 3 more clicks. (about 1 turn past the first soft click) That was perfect for mine anyway.
