There sure is a lot of speculation, on how long it can operate before flinging it's innards all over. Look at one and you can see it's not adjustable in the traditional sense, no gimmicks to fiddle with. But it can be adjusted. The billet housing ain't going to blow up, nor the permanent magnet and it's reluctor. Maybe the ball bearings will go chinese fire drill on you. Nope nothing wrong. Just an over produced part with plenty of competition. If someone got an introductory manufacturing deal on over runs done when the regular production was away, then that explains the obvious under charge. It's not for a race car, just H.P. street as advertised. The manufacturer was tricked into thinking that they would have additional orders. Those foreign idot's have no idea of how many we will eventually need, and that's few since it's obsolete technology suitable for old cars, only. You, also can return it if not satisfied. How many people will actually need a mechanical dist. with out an economy vacuum advance, for H.P. street? 5 in my city, maybe.
