I dunno what the problem is, but align them and be done. It is a cheap system and IF there was an American system, I would not be using them. They are cheaply made and have piss poor quality parts. BUT...I can see when I drive at night now. There is no chance of me overdriving my lights.
Soon to have some MHS parts, cams, 'luminum block, lower compression, ported heads, autorotor, and need to make long tubes. I have almost all the stuff and need some #42-50s a bypass valve, and maybe a few other things.
