when #1 or #6 cyl is on TDC compression the cam will be on base circle and you will be able to move the dampener aways a bit either way from the slit being at zero (TDC) without there being any spring movement. If that is the case then going (1) turn on the dampener will put the slit back to zero (TDC) and you will now be on overlap which is what we want then at that position you can move the dampener till the springs are (1) the same height (compressed amount) and they both will be compressed SOME (2) & going back & forth a bit on the dampener they both move. (3) at that point get em equal & see where the slit is at
