I had the same problem when I rebuilt my twink, I could see that it had been like it before rebuild because the wear mark on the rubber damping guide was at an angle even though the guide was installed inline with the block face. I looked at all things and concluded that the cylinder head may have been machined incorrectly having the thrust grooves that locate the cams 0.100" too far back? In the end I spaced out the cam sprockets to align everything, it's been fine so far!
Looking from the crank sprocket up towards the cams you could see the misalignment airc, I have some pictures if you are interested?
