I was bumbed about this because I used to have MSF up all the time and MSO is not the same on Tapatalk. I'm not sure why the difference, But sitting at a gov comp all day everyday makes me want some MSO.
Yes you need to reset. Make sure the bolt through the crank isnt to long it is more likely to bend, also have someone hold the cams in place helps relieve some of the movement on the crank.
