just rebuilt the heads, put her back together, she want to fire but can not quite catch to keep running. I wondering about my timing. There are several notches on flywheel and a notch on the pull start wheel which one do I use and how do cam bolts align, I thought they just point up and down with lobes both down, help pleasse

I'm not familiar with the timing marks on a 125, but if you have the "T" mark on the flywheel lined up with the mark on the case and have the lobes on the cam facing straight down, it should be in time. If the piston is on TDC and the cam lobes are facing straight down, then it's got to be in time, regardless of where the marks are on the cam gear or flywheel.
