Oh, man, yeah, that's way too much slop.
Almost worse than an old, wore-out unit.
That's one of Mike's repops. Different critter.
I have one, and compared it to a fairly good shape OEM advancer. Found some subtle dimensional differences 'tween the two. My Mike's center disc has slots that are a few thou narrower than the OEM. The Mike's flyweight ears are much narrower than my OEM's ears. I was considering using the Mike's center disc with OEM flyweights, getting a close fit.
The way Mike's sells those things is goofy. The advance unit comes without the center disc. You have to buy the advance shaft to get the disc. AND, it's been torqued on there by who knows. If dimensional quality control is poor, who knows what combination, and clearances, you'll get.
Edit: When I examined my new disc, I found some burrs and rough machining in the slots. They'd have to be cleaned up before I'd use it...
