Hi all, Well, I'm going to check the valves for the first time this weekend:eek: . I have read the manual and many posts about it, but I'm still nervous about it. I don't think I will have a problem checking the gap, but if I have to make an adjustment I will be a nervous wreck until it all goes back together and it runs! Anyone have any tips, tricks, do's and especially DON'T do's? Thanks in advance for your input.
