if you have the chain preloaded in the direction of rotation with tension against the pin, it shouldn't be a problem. if you have slack in the chain, ie the pin is loose, it will never be repeatable.

After you insert the pin, you will have to rotate the the cam in the opposite direction of rotation while holding the crank steady. this will retard the cam. check timing/lift. if too retarded, advance the pin one location and verify again. at this point you know that the slack is removed from the chain and you can begin tightening the cam nut.

i do have to comment that i find the design completely insane that the nut is not self tightening with the direction of rotation...
